Only Comark offers thermometerswith Biocote® antimicrobial technology

As an extra level of defence against cross-contamination, all the latest Comarkinstruments are manufactured with BioCote®

antimicrobial technology impregnated intothe instrument surfaces, keypads and probe handles.

The technology utilizes silver, a naturalantimicrobial that helps prevent the growth ofbacteria, mould & fungi and lasts for the lifeof the instrument. When micro-organismscome into contact with the silver, their abilityto reproduce is inhibited and they die.

A recent trial by BioCote Ltd and TheUniversity of Wolverhampton Science Park

canteen was conducted to compare micro-organism levels on a BioCote®

treated Comark thermometer with anuntreated thermometer. The trial was carried out over an 8 week period.

Swabs were taken from the thermometercase, keypad and probe handle beforeand after each use and the number ofcontaminating bacteria was counted.The treated instrument showed a dramaticreduction in microbe levels, proving beyondany doubt that BioCote® protectedinstruments are significantly cleaner andsafer to use in sensitive environments.

The actual result was a massive 92.73% reduction in microbe levels!

Stop!Think how yourbusiness could benefit from BioCote®

protected instruments.

Infrared ThermometersFor safe, non-contact surface temperature measurement.

Non-contact temperature measurement is a useful tool throughout the food industry. Apart from reducing risks from cross-contamination, non-contact also means lesswaste as it avoids destructive tests on valuableproducts. Infrared thermometers allow quicknon-contact temperature checks to be carriedout and if a problem is identified, furtherinvestigation can be undertaken using apenetration probe. Comark offers two infraredthermometers, FoodPro and FoodPro Plus. The following features apply to both.

FoodProInfrared thermometerSimply point the instrument at the area to be measured and read off the temperature on the display.

• Measurement range: –30°C to+ 200°C, switchable to °F

• Accuracy for targets at –30°C to +65°C: 1°C

• Accuracy for targets above 65°C: ±1.5% of reading

FoodPro PlusCombined infrared and probe thermometerSimilar to the FoodPro but witha wider infrared temperaturerange, a countdown timer and a flip-down penetrationprobe for more accurate confirmation of temperaturewhere a potential problem hasbeen identified.

• Measurement range (infrared):–35°C to +275°C

• Measurement range (probe): –40°C to +200°C

• Infrared accuracy for targets at –30°C to +65°C: 1°C

• Infrared accuracy for targets above 65°C: ±1.5% of reading

• Probe accuracy between –18°C and +65°C: ±0.5°C

• Indicator lights to warn ofpotential problems

• Illumination light identifiestarget area

Choosing a Temperature ProbeA comprehensive range that covers virtually every temperature measurement application.

Comark produces one of the largest available ranges of

temperature probes, with a probe for almost every application.

There is a special probe design and build facility so if you can’t findwhat you need within the standard

range, Comark can either modify anexisting probe or supply probes to

customer designs.

Probe CategoriesComark standard probes fall into four maincategories and each includes probes with different sensor types:

Penetration probes are used for measuring the internal, or core temperatures, of solid and semi-solid materials.

Surface probes are designed for maximum contact with the surface to be measured.

Air probes are for measuring air and gastemperatures, but also include food simulant and damped sensor probes.

Immersion probes measure the temperature of liquids and semi-solids.

Where required, UKAS certificates of calibration can be provided for probe andthermometer combinations.

Choosing the right sensorThe choice of sensor will determine themeasurement range, the accuracy and the responsetime. The sensor type must also be compatible withthe thermometer you use. Comark standard probesuse two basic sensor types:

1. Thermocouples. These consist of two wiresmade of dissimilar materials joined together at themeasurement tip (the hot junction) and connected at the other end to the instrument (the cold junction).The two main thermocouples used in Comark foodthermometers are Types K and T. See opposite forthermocouple limits.

The Type K Thermocouple has a wide measurementrange, responds quickly to temperature changesand is suitable for general food applications.

The Type T Thermocouple also responds quickly to temperature changes and generally providesgreater accuracy, but it is effective over a narrowertemperature range.

2. Thermistor (PST) is a semi-conductor sensorand provides exceptional accuracy but over a muchnarrower temperature range.

Probe Leads

Comark probe leads are matched to the intended applications for the probe. The materials used are:

PVC – PVC coiled leads provide ease of use in ambient temperatures of up to +70°C.

FEP and PTFE – These materials are especially suited to foodprobes and can be used in sub-zero temperatures. Steel braidedPTFE leads provide greater strength.

Fibreglass (FG) – Fibreglass insulated leads are used for specialapplication probes where the lead could be subjected to very highambient temperatures of up to +400°C.

M: Sub-miniature

B: Bipole

L: Lumberg

L8: 8-pin Lumberg

Thermocouple Limits

Choosing the right probeWithin the Comark standard probe range you’ll findprobes for general duties as well as ones for morespecialist applications. Try to match the probe to the job. For example, a low mass flexible air probe is better suited to accurate air temperaturemeasurement than a penetration probe which will take too long to stabilise.

For solid and semi-solid materials use surfaceprobes for surface measurements. Specialist optionsinclude probes with a rigid flattened stem for slidingbetween packs of frozen foods on a pallet or aspecially weighted griddle probe to ensureconsistent cooking temperatures.

Use penetration or immersion probes to checkinternal temperatures. Where holes need to be drilledin solids, use a thermocouple or thermistor probeand make sure it’s inserted to at least 6 times its

diameter. You can also use a thermal transfercompound for improved accuracy. Alternatively acorkscrew probe may be most appropriate.

For liquids use an immersion probe, or you can usecertain penetration probes, but check for possiblecorrosive effects on the sensor first and agitate theliquid for a faster response.

For air and other gasses use an air probe. Response times are affected by heat transfer around the sensor, and the smaller the sensor, the faster the response time. Response is alsoaffected by air movement. Food simulant anddamped sensor probes have a large mass aroundthe sensor to slow response times so they don’ttrigger alarms when fridge or freezer doors areopened or during defrost cycles.
