INTRODUCTION: for industrial calibration

DataBook 3 contains Isotech products designed forIndustrial Temperature Calibration. This is an ambitiousclaim given that those faced with the task of calibratingindustrial sensors encounter sensors of widely varyingsize, temperature range, accuracies and type.

In this DataBook calibration solutions exist for accuraciesfrom 1ºC to less than 0.001ºC, temperature ranges frombelow 0ºC to 1200ºC, from handheld to bench topdevices. Products include Dry Block Calibrators, LiquidBaths, High Temperature Furnaces, PrecisionTemperature Indicators, Temperature Sensors withsupporting services, UKAS Calibration and software.

The industrial calibration products have been enhancedand upgraded benefiting from new instrumentation andsuperior performance. PC interfaces and supportingsoftware have been introduced as standard along withother enhancements making the products betterspecified, better value and easier to use.

Benefit from Isotech's premier UKASCalibration Laboratory

Many manufacturers of temperature calibrationequipment do not operate accredited laboratories. AtIsotech we remain unique in that in addition to amanufacturer of equipment we also operate a full scaleUKAS laboratory calibrating both our own equipmentand a full range of temperature equipment for our clients.

Benefit from Experience

Isotech fully understand the calibration needs of ourcustomers. We design and specify products accordingly.Isotech make available full evaluation reports withuncertainty calculations and publish uncertainty graphs.

Dry Blocks from other manufacturers are sometimesspecified in interesting ways, such as Minimum OperatingTemperature -30ºC but with an ambient of 5ºC, Isotechlabs and workshops are kept close to 20ºC! We don'tspecify performances of thermometers only at 0ºC wealso tell you what it is like at high temperatures. Isotechunderstand the difference between resolution andaccuracy, between accuracy and uncertainty, between"specmanship" and the firm evidence an auditor wouldexpect to see.

Benefit from Innovation

The international award winning ISOCAL-6 series set newstandards in temperature calibration, Dry Blocks nowinclude a PC interface and software as standard. TheI-CAL software can automatically capture temperaturestamped images with a camera, another first fromIsotech.

Liquid Baths:Temperature Range -25°C to 250°C

Portable Stirred Liquid Baths have a large well which isfilled with liquid. The liquid is stirred and heated orcooled to the desired temperature.

The temperature sensors are placed directly into theliquid avoiding the need for specially drilled blocks. Theyare ideal for awkward shaped and short sensors. Angledprobes will not readily fit into a metal block but can beplaced into the liquid.

Accuracies are in general better than dry block baths dueto lack of air gaps and the temperature uniformity of thestirred liquid.

Liquid Bath Advantages

Calibrate awkward shaped sensors.

High Accuracy.

Excellent temperature uniformity.

Sensors placed into liquid, no specially drilled insertsrequired.

Portable Liquid BathsTo calibrate temperature sensors to 250°C look nofurther than these portable stirred liquid baths. TheHyperion calibrates from -25°C (At ambient of 20°C) to140°C and the Drago from 30 to 250°C. The calibrationvolume is 65mm diameter and the useable depth of160mm gives more than twice the volume of alternativeproducts.

Stirred liquid baths are suitable for temperature sensorsof all types, shapes and sizes, angled probes, bentprobes and short probes with large mounting heads canall be readily accommodated, an advantage over DryBlock Calibrators.

If a laboratory standard temperature indicator is addedmuch greater accuracies than those from Dry Blocksalone can be achieved and with suitable referencethermometers performance of up to 0.005°C isachievable.

These models include a high accuracy inbuilt digitaltemperature indicator and a reference probe. Thisindependent measurement system is used as a referenceto which the thermometers under test are compared.This method gives good accuracy largely eliminatingtemperature gradient and loading errors and providestraceable temperature calibration.

Introduction to the Isocal-6 Calibration System

®

What is Isocal-6?

Isocal-6 is a range of calibration systems that cancalibrate all types of thermometer and share commonfeatures.

What is special about the Isocal-6 range?

Previously temperature calibration baths werespecified by type, e.g. A Dry Block Bath, A Liquid Bathetc.

With the Isocal-6 different accessories are added to theIsocal-6 to allow it to be used in many different modesproviding a solution for all temperature sensorcalibration requirements.

What are these different modes?

The Isocal-6 includes a removable insert as standard foruse as a Dry Block Calibrator, with optional accessoriesthe Isocal-6 can perform as:

A Stirred Liquid Bath

A Stirred Ice Bath 0ºC Reference (Cooling models only)

A Blackbody Source for IR thermometers

A Calibrator for Surface Sensors

An ITS-90 Fixed Point Apparatus

What if only one option is required?

One of the advantages is that you need only purchasethe desired option but other accessories can be addedat any time.

What temperature range is covered?

Different models cover the temperature range frombelow -40ºC to 250ºC, above this maximumtemperature it is not practical to use a stirred liquidbath. For higher temperatures see the other Dry BlockCalibrators that go to 1200ºC, many with accessoriesfor Surface Sensor and Blackbody use.

What Performance can be achieved?

This varies on the way it is used, for an ITS-90 fixedpoint apparatus uncertainties of better than 0.001ºCcan be achieved - see the uncertainty graphs for othermodes of operation.

International Support?

Isotech have a global network of authorised agents anddistributors providing both before and after salessupport.

Made to last?

All Isotech products are engineered for long life. If youhave ever tried to get inside the dashboard of a motorcar you will appreciate that cheapness goes withinaccessibility for repair and maintenance. Isotech’sproducts are designed for long life, easy repair,accessibility and maintenance.

The ISOCAL-6 is currently subject to a patentapplication (reference 9900158.8).

The EUROPAPLUS offers an exceptionally wide operating range in an easy to use portable package. Aspart of the ISOCAL-6 series the EUROPAPLUS can be used as a Dry Block, a Liquid Bath, a BlackbodySource for infrared thermometers, a Surface Sensor Calibrator and for performance to a few mK(0.001ºC) ITS-90 Fixed Points. The EUROPAPLUS is available in two models, the BASIC (B) and the SITE(S). The B model includes a sophisticated temperature controller with a dual display for SetTemperature and Dry Block Temperature, refer to page 27 for further details. The S model additionallyincludes an in-built digital indicator to which an external temperature sensor can be connected.

For Dry Block use the unit under test may be compared to the controller value, Isotech recommendthe use of an external probe connected to the indicator of the Site model (see page 23) whichcompensates for the temperature gradient and loading errors. This gives greater accuracy andtraceability meeting the requirements of ISO 9000 and other quality standards.

For liquid bath, surface sensor and blackbody use an external standard probe should always be used,either with the S models indicator or an external indicator, e.g. an Isotech TTI model. For laboratoryuse the EUROPAPLUS can be used with a laboratory performance temperature indicator such as one ofthe Isotech True Temperature Indicators (TTI).

Includes as standard: Windows Software, Computer Interface and a Ramp to Set Point Feature.Increased resolution of ±0.01 available throughout the range via the PC interface and from-19.99 to +99.99 locally on the auto-ranging front display. The controller features multi-pointblock to display correction giving good absolute accuracy.

For Dry Block use the unit under test may be compared to the controller value, Isotech recommendthe use of an external probe connected to the indicator of the Site model (see page 23) whichcompensates for the temperature gradient and loading errors. This gives greater accuracy andtraceability meeting the requirements of ISO 9000 and other quality standards

For Liquid Bath, Surface Sensor or Blackbody use an external thermometer should always be used -either with the S model or the B model and a separate stand-alone indicator. For laboratory use theVenus can be used with a laboratory performance temperature indicator such as one of the IsotechTrue Temperature Indicators (TTI).

Proven QualitySlim Fixed Point Cells

The International Temperature Scale of 1990 applies World-wide; it includes specified fixed points -fundamental constants of nature. The majority of which relate to the freezing point of a pure substance,e.g. Pure Aluminium freezes at 660.3230ºC. These standards are generally kept by Primary andNational Laboratories. Isotech's Databook 1 includes these Primary Standards and associatedequipment. Databook 2 includes a range of more affordable fixed points that are used in SecondaryLaboratories and for extreme accuracy industrial calibration.

Many of the products featured in this Databook can be used with Fixed Point Cells enabling a modestlyconceived industrial laboratory to be upgraded if and as the requirements arise. These Fixed Points arecalled Slim Cells because they are somewhat smaller than the cells normally used for Primary Standards.

These more economic cells are available in a number of constructions including metal clad as well asquartz glass clad cells. The metal cells are pure to 6N, 99.9999% pure and are sealed with 99.9999%pure argon at one atmosphere.

The Water Triple Point is perhaps the most important of the fixed points and there is a choice of twomodels, the smaller for the ISOCAL-6 Range, and the larger cell for the Oceanus-6.

The table opposite shows the Slim Cells available for the products in this databook. For furtherinformation relating to fixed point calibration please refer to Databook 1, Databook 2 and visit ourweb-site.

Isotech's Slim Fixed Point Cells can be used to calibrate temperature sensors, either as the metal withinthem melts, or as it freezes. Typically, says CCT/96-8, a 6N pure cell will melt over 80% of its plateauwithin ±1mK. Exceptionally Isotech's Gallium Cell will melt over ±0.2mK.

Allowance must be made for the sensor being calibrated, sensors with short sensing lengths will addno additional errors to the above but other types with longer sensing lengths will add additionaluncertainties. An article is available from Isotech detailing stem conduction errors, please ask for yourcopy, free with our compliments.

Two examples showing the cell/apparatus/sensor performance are illustrated on the facing page.

Introduction to Dry Block CalibrationDry Block Calibrators

Isothermal Technology manufacture a full range oftemperature calibration equipment for PrimaryStandards used in National and Primary Labs, forSecondary Lab Equipment used in accreditedcalibration laboratories and through to the Dry Blocksfeatured here. Customers include the worlds largestPrimary Standards Laboratories, AccreditedLaboratories (UKAS, DKD etc), large multinationalcompanies, research organisations, manufacturingetc. Eighty percent of Nations rely on Isotech tosupply their country's standards. This is not aresponsibility taken lightly and Isotech constantlyinvests in its own full scale UKAS (formerly NAMAS)accredited laboratory. Isotech issues UKAS certificatesfor fixed point cells, thermometers, indicators and dryblocks. Isotech have issued several thousandcalibration certificates and carried out severalthousand measurements on Dry Blocks. We calibrateall types, not just our own.

The benefit of this experience, and the knowledge ofyears of manufacturing Dry Blocks is invested backinto these products with the goal of constantimprovement. In recent years the number ofproducers of Dry Blocks has increased dramatically,whilst many look similar (and some look surprisinglysimilar to our established models) they are often verydifferent inside and can perform very badly.

The Dry Block Calibrators complement with theISOCAL-6 range. Above temperatures ofapproximately 250ºC it is not practical to use stirredliquids due to fumes, risk of ignition and safetyconsiderations.

Isotech's higher temperature calibration bathsincorporate as many of the Isocal-6 options as is safeand practical to provide.

Dry Block Check ListBefore you purchase check:-

1 - Does the Producer Have anAccredited Laboratory?UKAS accreditation, “is the means by which, in thepublic interest, the integrity and competence ofindependent evaluators is confirmed and declared”.Isotech can issue a UKAS certificate with theperformance expressed in the manner that you willneed, not to some confusingly expressed specificationthat is made with no confirmation of integrity andcompetence.

2 ExperienceDoes the producer have experience? Do theyunderstand the difference between accuracy anduncertainty? Can they tell you how to calculate theuncertainty of a probe being calibrated in the block?Isotech can.

3 ExpandableCan the Dry Block be used with other sensors? Arethere accessories available for future expansion? WithIsotech products they are.

4 - PC SupportCan it be connected to a computer? Is there softwareavailable, can it be automated? Isotech Dry BlockCalibrators have a range of software options.

5 - DocumentedIs the bath fully documented? Can you download afull evaluation report from the Web Site? Does itcome with a comprehensive handbook and tutorial? Istraining available? Isotech provide all of these free ofcharge.

6 PracticalIsotech Dry Blocks are practically designed with astrong metal case, and are a compact portable size. Ifyou are going to carry it around don't forget to checkthe size and weights. It is surprising how large someother blocks are, even though they take the samenumber of probes. Beware if the specification doesnot include the weight.

7 ValueCheck the prices, all the above come at an amazinglycompetitive price if you buy from Isotech.

Introduction to Dry Block CalibrationDry Block Calibrators

ImprovementsNew in this Databook are the PLUS models. Isotech workedwith a world leader in temperature control technology todevelop easy to use Dry Block controllers and Indicators.Now Isotech plug-in controllers are exceptionally easy touse with a clear user interface. Power feedback is usedto stabilise against supply voltage changes, a digital filtercircuit ensures high integrity of measurement withoutdrift, rejecting 50/60Hz pick up and filtering out othersources of noise. Resolution is increased. The indicatorshave universal thermocouple inputs and we have addeda PC interface and software as standard. Check theindividual models for full details. Windows software isnow provided as standard, with expandable options tocalibrate up to 16 sensors at a time. The new I-CALsoftware can event capture images for automaticcalibration of hand-helds etc.

Inbuilt IndicatorThe SITE (S) models include an electronic temperatureindicator that can be used with a 100Ω ResistanceThermometer, Thermocouples, (K, N, R, S, L, B, PL2, T,J and E) and DC process inputs including 4-20mAcurrent transmitters . A reference thermometer can beconnected or for complete flexibility the in-builtindicator can be used to show the value from a sensorbeing calibrated.

Using Isotech's Dry Blocks TraceableCalibrationFor best practice the recommendation is that acalibrated probe is placed into the Dry Block Insertand the thermometers under test “can be related toappropriate standards, generally international ornational standards, through an unbroken chain ofcomparisons”. Thus meeting many quality systemsincluding requirements of ISO 9000.

Using the Dry Bock itself as the Reference (orstandard) raises a number of issues, such as how is theuncertainty of the Dry Block calculated. In practice, itcan vary significantly, and there are some poordesigns from many suppliers where it is not possibleto achieve this in a satisfactory manner. Recently,International Guidelines have been published fromthe EA (European co-operation for Accreditation) thatgive guidance, and requirements, for the calibrationof Dry Blocks (EA10-13). For the most demandingapplications we continue to recommend that areference probe is used, the same method as used insecondary temperature laboratories, but for lessdemanding calibration, and the quick testing ofsensors the Dry Block can be used without a referenceprobe, refer to the Dry Block’s Evaluation Report fortypical performance.

Dry Block CalibratorApollo 1 & 2

The Apollo Dry Block range offer a complete self contained and simple solution for the checking andcalibrating of temperature sensors. The sensors under test are placed in the large block and one of thefive preset temperatures is selected, the temperature from the sensor is then recorded against thevalue from the Apollo's UKAS (formerly NAMAS) Calibration Certificate. This calibration certificate isincluded as standard. The moderate temperature range, deep immersion depth and fixed block allowit to be issued without the need for an external standard.

The Apollo is widely used as a reference standard in hospitals, local government and food industriesetc. The Apollo has been developed from Isotech's very first dry block and has a long history ofsuccessful use. See the calibration history chart of a typical bath.

The block has four 8mm pockets and four 19.5mm pockets all 160mm deep.

Dry Block CalibratorGeminiPLUS 550/700 LRI

The GeminPLUS LRI (Large Removable Insert) Dry Block range offers industry-leading performance in aneasy to use portable package - ideal for the calibration of thermocouples and platinum resistancethermometers.

It differs from the GeminiPLUS models in that it has been designed to have a large removable block witheight 8mm pockets, supplied as standard. Alternatively a block can be custom drilled allowing manyprobes to be calibrated simultaneously without the need for inserts and ensuring excellenttemperature uniformity.

GeminiPLUS LRI is available in two models, the BASIC (B) and the SITE (S). The B model includes asophisticated temperature controller with a dual display for Set Temperature and Dry BlockTemperature. The large block has the benefit of higher capacity but with longer heating and coolingtimes compared to the fast response models such as the Jupiter 650.

The S model includes a built in digital indicator to which an external standard thermometer can beconnected giving greater accuracy eliminating temperature gradient and loading errors. For labaccuracy the GeminiPLUS LRI can be used with a high-end temperature indicator such as one of theIsotech True Temperature Indicators (TTI).



New! The Site model can now be used with the supplied Cal Notepad software to testthermostats. Cells

Isotech has a wide range of Dry Blocks to suit probes requiring a large immersion depth. Theseproducts feature large and deep calibration volumes. As such they are less portable then the earlierDry Blocks but have higher capacities and retain outstanding temperature uniformity, this uniformityis so good that these larger products are also featured in DataBook 2 as apparatus for SecondaryLaboratories to realise the Fixed Points of ITS-90.

For comparison calibration the Oberon should be used with an insert. The insert has six pockets 8mmdiameter by 160mm deep which is suspended from the top of the heatpipe so that the height is useradjustable. For flexibility an accessory can be added for blackbody use.

The Oberon uses a specially designed stress free isothermal heat-pipe as its furnace that ensures avery low thermal gradient along the furnace core.

The heat-pipe is designed so that the inner wall is not subject to thermal expansion stresses from theouter wall before the heat-pipe reaches conduction temperature. The working fluid is permanentlyand safely sealed within the plasma-arc welded enclosure.

Connections are provided for a water supply of 0.5 to 1 litre per minute to cool the case of theOberon. Water supply and waste connections are provided. Use without cooling is not recommendedabove 700ºC.

Introduction to Temperature TestersTesters

Isotech Dry Blocks have the features and performanceto meet most calibration needs. Sometimes there areapplications where a compromise has to be made,with regard to size or price. An engineer forced tocarry a calibrator up a ladder and into a confinedspace might have to sacrifice performance for physicalsize. Where sensors of small dimensions and largeuncertainties are used.

Isotech have developed a range of products called“Testers”. They don't have the same immersiondepths that larger baths have, the blocks are smallerand the dry blocks do not have a PC interface.

What they do have is:

Outstanding Value

Compact Size with true handheld models

Wide Operating Ranges, from less than-35ºC to 650ºC in three models

Fast Response

QuickCalsThere are two QuickCal models, handheld, portableand capable of operating from below -10ºC to 350ºC.

35 to 650ºC Model 903Model 903 is slightly larger than the QuickCals butoffers a larger block and operation to 650ºC.

55ºC below Ambient to 140ºC Model 907Model 907 like the 903 is larger than the QuickCal butoffers a larger block and wider temperature range.

Small Hot PlateA small portable hot plate for testing surface sensors,use up to 350ºC.

Introduction to Temperature TestersTesters

Immersion depth is very important

When selecting a Dry Block Calibrator depth of immersion is very important. The chart below providesguidance in selecting a bath for immersion depth. Note that sensors with a long sensing length willrequire greater immersion. The chart is general and applies equally to all dry blocks - not to a particularmodel or manufacturer.

Immersion depths for various diameter thermocouples or thermistors in a dry block bath

Example shows 0.3% stem error for a 15mm diameter thermocouple immersed 160mm in a dry block.

Note 1. For sensors immersed in stirred liquids the diameter of sensor can be doubled, or the minimum depth halved.

Note 2. The sensing length must be added to the above immersion depth calculation

N.B. The above gives a good guide, however each sensor will be slightly different.

For full information on selecting the correct immersion depth for all types of sensors ask for our free 8 page immersion tutorial.

Temperature Test UnitQuick-Cal Range

Isotech's Quick Cal range of testers are ideally suited to the less exacting applications where ourlarger, better specified baths are unnecessary.

The Low Temperature Quick Cal covers the temperature range of -15ºC to +140ºC, making it ideal forthe medical, sterilisation and food industries.

The High Temperature Quick Cal covers the temperature range from 30ºC to 350ºC.

Both have interchangeable inserts, so you don't have to buy another calibrator each time you find anew diameter sensor to calibrate. The Low Temperature Quick Cal is particularly exciting since it canwork from a small 12 volt battery, making it truly portable, alternatively a mains supply is available with100V - 240V, 50/60Hz input.

The Low Temperature Quick Cal comes complete with two inserts, one blank and one drilled 6.8mmdiameter 120mm deep. Alternatively we can provide pre-drilled inserts to suit your needs. Eachcalibration well is 13mm diameter and 120mm deep.

The High Temperature Quick Cal has a single larger well and interchangeable inserts, 25mm indiameter by 120mm deep. Blank and other special drillings are available to order. The HighTemperature Quick Cal is supplied 100-130 or 200-250V AC, 50/60Hz.

The handbook which accompanies the Quick Cal contains helpful advice on how to get the best fromyour calibrator. Accessories for the above include a carry case, alternative inserts and a rechargeablebattery for the Low Temperature Quick Cal.

Thermocouple Simulator870 Isocal

A method of accurately calibrating any thermocouple temperature measurement or control system isavailable from Isothermal Technology Limited. Replacing the normal calibration “Trolley” containingMicrovolt Generator Ice Point Reference Chamber and Digital Voltmeter by a pocket sized calibrationunit complete with its own battery and cold junction compensation.

To use the unit, simply follow the steps outlined below:

1. Disconnect the normal Measurement Thermocouple.

2. Substitute the Isocal unit.

3. Select one of ten switch preset temperatures on the front of the Isocal.

4. Check that the measurement or indicator system reads the preset temperature.

The ability of the Isocal unit to simulate any preset temperature with and without cold junctioncompensation, enables the user to substitute the electrical equivalent of the thermocouple output towithin a fraction of a degree and inject the signal into almost any kind of measuring system. Modelsare available for all common thermocouple material to IEC 584 tables.

PRT andPRT / Thermocouple Indicators

Our TTI range are True Temperature Indicators, thismeans individual calibrated sensors can have theircalibration values programmed into the TTI. Theinstrument then digitally 'calibrates' to suit the probeand the TTI shows the corrected value accordingly.Additional manual measurements are not required tocompute the precise temperature readings since theseare displayed correctly, miscalculation errors areavoided.

These instruments both have two channel operation,which allows for a calibrated reference probe to beused on one channel, with the unit under test on thesecond, permitting simultaneous comparisoncalibration which eliminates many errors compared to asingle channel system that calibrates sequentially.

When several sensors need to be switched Isotech hasa range of Selector Switches to accompany theindicators, along with software to ease and automatethe instruments use.

True SurfaceTemperature Measuring System

This is a true temperature indicator for use with surfacetemperature measurement, ideal for use with the smallhot-plate model 983, see page 44.

Semi Standard Resistance Thermometersand Thermocouples

This section includes a range of “Semi Standard”thermometers that can be used with the TTI’s. Theseprecision semi standards are more rugged andaffordable than the standard thermometers featured inDatabooks 1 and 2 – and ideal for most industrialapplications.

FixedResistors

Isotech have a miniature resistor with an ultra lowtemperature coefficient, model 836, with accuracies of±0.005% and temperature coefficients of less than1ppm. These resistors offer an outstanding cost toperformance ratio and will find use alongside a modelfrom our TTI range and in other areas of industrialcalibration.

High Accuracy PRT and Thermocouple Thermometer

TTI-7

The TTI-7 is a very high accuracy multi purpose digital thermometer for both platinum resistancethermometers and thermocouples. Laboratory users will welcome the features to eliminate Thermal EMFErrors and Self Heating Errors along with provision to store the calibration data of up to 20 PRT probes.The rugged aluminum case, internal battery pack and integrated power supply ensure reliable portablefield use for demanding measurement applications all at great value for money.

Dual Channel input allows a probe on Channel B to be calibrated against a standard on Channel A -directly compare any combination of PRT and Thermocouple. The TTI-7 supports ten thermocoupleTypes, B,C, D, E, J, K, N, R, S and T and Pt100 thermometers. Connect up to 16 sensors via the optionalswitchboxes, Model 954 and 958.

Data Logging and Statistical AnalysisThe TTI-7 includes an inbuilt data logger internally storing up to 4,000 date and time stamped readings. Recall thedata from the front panel or send to a PC or Printer via the PC interface which is included as standard. The powerfulmath function enables statistical analysis of the captured data, mean, max, min, peak and standard deviation.

UsabilityEase of use, password protected digital calibration and a large clear backlit LCD graphics panel ensure the TTI-7 is adelight to use. Resistance thermometer connections are via LEMO connectors. Both sub miniature thermocouple andstandard thermocouple plugs are accepted directly into the thermocouple inputs with no need for further adapters.

Why the TTI-7?The TTI-7 has the features you need for high accuracy temperature measurement. With resistance thermometers usedat high temperatures unwanted thermal EMFs are generated, the TTI-7 can take two measurements switching thepolarity then computing the average to eliminate this error source. Many other instruments lack the ability to eliminatethermal EMFs. The thermal EMF error can be greater than the quoted accuracy of an instrument, if you need smallmeasurement uncertainty for high temperature PRT work you need this feature.

High accuracy, highest accuracy is for Pt100 inputs, the TTI-7 Uncertainty of Measurement (1 Year) in the range -100°Cto 500°C is 0.01°C. Watch for specifications that quote the value at -100°C and then get larger as the temperaturerises. The TTI-7 is optimized over the most frequently used and useful temperature range. For thermocouplemeasurements the automatic CJC is far better than 0.1°C at 20°C. Great design care was taken, both thermocoupleinputs are measured with separate Pt100 sensors. This approach gives outstanding CJC performance, again a pointto check against other instruments which can have significantly less performance.

For 3 & 4 Wire PT100’sTTI-6

The TTI-6 is a high precision portable thermometer for metrology and other exacting laboratoryapplications, the TTI-6 is a proven instrument used World-wide as a laboratory and site standard. It isparticularly suitable as the reference standard for temperature calibration baths.

The TTI-6 Digital Thermometer utilises highly advanced microprocessor circuit design to achieveexceptional measuring accuracy, linearisation conformity and stability in a versatile but easy to useconfiguration.

Based on a high resolution 20 Bit Analogue to Digital convertor, all measurement computations areperformed digitally without drift. The 5 LED display provides a readout to 0.01ºC over the entire-199.99ºC to +849.99ºC range; alternatively ºF, Kelvin or Ohms values can be displayed up to 999.99units.

Single or dual Pt100 3 or 4 wire sensors are accepted, the TTI-6 will automatically recognise and select3 or 4 wire mode. Display of input A, B or A - B (differential) can be selected; a differential “zerofunction” allows sensor accuracy differences to be eliminated for accurate differential readings.

Calibrated sensors can have their calibration points programmed into the TTI-6 via a personalcomputer using Isotech Software. The instrument then digitally self calibrates to the probe(s)providing corrected temperature readout to give optimum system accuracy.

A common application is for the comparison calibration of a sensor on channel B against a referencestandard on channel A. With one of the Selector Switches several sensors can easily be compared toa standard probe on A.

The instrument includes a UKAS certificate as standard (simulation calibrated). Isotech also offers acomplete system calibration (probe and instrument combined). Refer to Databook 5 for details.

Platinum Resistance ThermometersSemi-Standards

In most industrial laboratories the costly and mechanically fragile SPRT is unnecessary. For theseapplications the uncertainties may be larger, and hence the Isotech range of semi-standards may bea more practical choice. Usually made in stainless steel sheaths 6mm in diameter, with an Ro value of100Ω and an (R100-R0)/R0 of 0.385. A number of configurations are available since particularcharacteristics might be required such as short sensing length, fast response, or applicability to aparticular temperature range.

In this collection of semi-standards Isotech has examined not only the uses that customers put themto but also the equipment that is used to calibrate them. Most units are now a little longer and havea slightly wider temperature range than our previous products. The stability of the semi-standard willdepend upon its range of usage; your semi-standard should remain with those uncertainties betweensuccessive annual calibrations, unless you drop it or otherwise mechanically shock it. Our semi-standards are now fitted with a handle and strain relief bush for the cable, except where otherwisestated. All are made with our own high quality 100 ohm detectors and completely assembled andcalibrated in-house in our UKAS accredited and supervised Laboratory. Calibration is available withfixed points for the best uncertainties and to give the highest confidence possible.

Please note that stem conduction accounts for the biggest sources of errors during calibration.Remember that for a given immersion depth stem conduction is dependent on the temperaturedifference between the sensing element and ambient temperature, and on the total conductance ofthe thermometer assembly. It is sometimes thought (mistakenly) that a shorter thermometer will besubject to less stem conduction.

Semi-standard thermocouples without cold junction.

This range is based on our popular standard thermocouples. We receive many requests for differentsizes, length and thermocouple materials. From our experience in calibration Isotech have been ableto select those thermocouple combinations and sizes which give the best and most stable results.

Below is an extract from Isotech's UKAS schedule that shows the laboratory's best capability tocalibrate thermocouples. The uncertainty of a particular thermocouple will depend on factorsincluding how it is calibrated. System uncertainties will also vary with which indicator and calibrationbath that the sensor is used with. Most of the products shown here include system uncertainty graphs;please contact Isotech for details of any combination not shown. There is also a range of laboratorygrade and standard thermocouples, Databooks 1 and 2.

These semi-standards do not have a cold-junction. This feature is usually incorporated in the indicatorto which the semi-standard is connected. We offer the type N, R or S semi-standards either with1 meter leads, with standard plug or miniature plug.

8 Way Selector SwitchSelector Switch

Isotech produces two eight way selector switches, one for resistance thermometers Model 954 andModel 958 for thermocouples. These switches have been designed for use with a model from our TTIrange.

The switches allow easy selection of connected sensors. They can be operated from either the frontpanel switch or from an RS232 interface that is provided as standard. Channel status is indicated viafront panel LEDs. The Selector switches can be located adjacent to the sensors being calibrated,giving more flexibility than a permanently connected or stacked system.

The PRT Switch has 4mm Terminal Posts that can accept bare wires or 4mm plugs. The thermocoupleswitch has eight miniature thermocouple connectors. These thermocouple connectors are thermallybonded to a platinum resistance thermometer that measures the temperature of the connector andhence the “cold junction”. The TTI range temperature indicators feature the ability to measure aremote cold junction and this permits a mixture of thermocouple types to be connected through thebox.

The I-Cal software supports Switchbox models 954 and 958 and, for automatic operation, two boxescan be connected together with a “master / slave” lead allowing them to be controlled from a singleRS232 port and up to 16 sensors to be switched. The software can automatically switch between theboxes and connect the appropriate output to the TTI. This 16 channel operation is not convenientwithout the software and manual operation of two boxes together is not recommended. SeeDataBook 2 for a 16 channel manual switch, the Model 947.

Advantages

Use with TTI-6 and TTI-7 easily switch up toeight sensors manually or with RS232.

RTD and Thermocouple Models.

Use with I-Cal Software for automaticswitching and temperature calibration, add asecond box (either type) to calibrate up to 16Sensors.

Switches are stand-alone allowing them to bepositioned anywhere in a laboratory for mostefficient operation.

The function of hermetic sealing is to eliminate the ingress of moisture and oxygen both of which playa role in both short and long term degradation of unsealed resistors. A further enhancement in bothshort and long term stability is achieved by oil filling. The oil also acts as a thermal conductor allowingthe device to accept short periods of overload without degradation.

With accuracies of ±0.005%, resistance range from 5 ohms to 3.3 megaohms and long term drift ofless than 5ppm, these devices are virtually secondary standards that can be carried in sets for daily orperiodic calibration of factory systems.

Temperature Measurement System944 True Surface

350ºCto

30ºC

The fundamental problem with surface temperature measurement is that it is subject to large stemconduction errors, also because heat conducted from the surface of the hot-plate causes a localisedcold spot to be created which means that the temperature indicated by the hot plate is not necessarilythe temperature at the point of measurement.

An ideal system would not disturb the heat-flux from the hot-plate.

During 1993 such a system was described (ref. “Progress in Contact Thermometry” 1993 B. D. Foulis)and Isotech have the inventors permission to make and market the device World-wide.

Principal of Operation

A fine wire type N thermocouple is used as the surface temperature sensor, a second junction 2 to3mm along the thermocouple, senses the temperature difference due to heat flux along the sensor.A heater heats the thermocouple stem until the temperature gradient is zero, thus creating ameasurement without stem conduction, or disturbance of the hot-plate's surface.

The 944 can be used with the Isotech Small Hot Plate model 983, see pages 44 - 45. A traceablecalibration certificate is available to order.

Key Features

IntroductionSoftware

SoftwareNewly developed software provides ease of use and routes to fully automatic temperature calibration.

CalNotePadIncluded as standard with the calibration baths and TTI indicators. This permits you to connect both an indicatorand the calibration bath to the PC. You can view data on clear configurable chart displays, log data to file andcontrol the calibration bath.

I-calA software application that can automatically calibrate up to 16 temperature sensors, it provides an expandablelow cost route to automatic calibration with I-cal Capture you can store pictures (along with time and temperaturedata) to enable, for example, dial thermometers to be calibrated automatically; return to a set of images of thedial captured at each calibration temperature!

Virtual Lab TechnicianVLT provides a turnkey solution for the automatic calibration of temperature sensors. Consisting of a PCWorkstation, Selector Switch, TTI Indicator and calibration bath(s) it provides a combination of computer hardware,calibration equipment and software to automate the calibration of temperature sensors, further details inDatabook 2, a demonstration disk is available on request and full details can be found at www.isotech.co.uk

The Dry Block Calibration Baths included in this DataBook have been enhanced to feature serialcommunications as standard. The baths have a serial interface (RS422) as standard, this allows anumber of calibration baths to be connected together in a daisy chain.

A special lead assembly is provided which converts the RS422 to a PC's standard RS232 port.

This innovative approach allows you a simple trouble free way of connecting a number of baths to asingle PC's RS232 port.

SoftwareCal NotePad

The purpose of Cal NotePad (CNP) is to automatically log and display the temperature of an Isotechcalibration bath together with the unit under test. Cal NotePad can be used with baths (or indicators)without PC interfaces by the user typing in values from the keyboard. The Cal NotePad can be used toidentify the operator and the unit under test. With the click of a button data is logged with time information,it is also possible to log continually.

The calibration bath temperature can be changed from the PC or from the calibration baths controller - CalNotePad will display the temperature changes as they occur on the re-scalable chart display.

For traceable calibration the unit under test should be compared to a calibrated standard thermometer. CalNotePad can record the actual temperature of the bath from either the in-built indicator of an Isotech SITEmodel or from a variety of external instruments see list. If the external instrument has two channels (e.g.Isotech TTI) then the unit under test may be connected to channel B for logging with CNP. Alternatively thevalue can be typed in from the keyboard. Similarly the calibration bath controller value, actual temperature,SITE indicator value or unit under test value may also be entered manually.

Then the manually entered data is combined with that gathered automatically and the resultant file can beopened in an external application such as Excel for the preparation of reports, certificates etc.

Cal NotePad is designed for ease of use, it will give a chart of the system. When the operator determinesthe system is stable - easily seen from the chart then clicking a button will record time, operator, serialnumbers of unit under test along with controller and indicator values.

Cal NotePad can be used for semi-automatic calibration, see I-cal for a fully automated calibration solution.

SoftwareI-Cal

I-cal is a new software application designed for automatic temperature calibration using Isotech products. Itis affordable, easy to use and modular.

In the simplest form it can be used with a SITE Dry Block Calibrator to automatically calibrate a single sensoragainst the block temperature.

To calibrate multiple sensors simply add an Isotech Selector Switch - there are two models; one for up toeight resistance thermometers and one for up to eight thermocouples. You can have a total of two boxes,any combination, to calibrate up to 16 sensors!

I-cal also supports models from our TTI range of indicators and with these you can easily build an automaticcalibration system to calibrate up to 16 sensors on the TTI's channel B, with a standard probe on channel A.The calibration results are saved to a text file that can be opened in your preferred application to create acertificate or report.

I-cal CAPTURE is suitable for the automaticcalibration of hand-held thermometers andsimilar devices. Previously hand-helds could notbe easily calibrated automatically because mostmodels do not have provision for a connectionto a PC. I-cal CAPTURE solves this by using alow cost camera. I-cal, as usual, monitors the dryblock bath / standard for stability, it then grabsan image before setting the bath to the nexttemperature. The image is captured with thedate and time to make a complete visual record(as shown).

Key Features

Use ISOTECH equipment to automaticallycalibrate temperature sensors.

Affordable and Expandable - A Selector Switchand or True Temperature Indicator can be addedto the Dry Block at any time.

Calibrate up to 16 sensors - Use twoswitchboxes to calibrate up to 16 sensors at up to10 temperatures.

Save Time - Set I-cal going, go home and returnto the calibration results!

Results saved to Text File - the calibrationresults are stored to a text file for you to process.

I-cal CAPTURE can save images - of devices likehandheld thermometers that can not beconnected to the PC.

A caption is added showing dates,time and the standard temperature.
