DRAEGER-TUBES® - MEASUREMENT SYSTEMS

INDEX


“A detector tube is a hermetically sealed glass tube containing an inert solid or granular material such as silica gel, alumina,resin, pumice, or ground glass.

The inert material is impregnated with or mixed with one or more reagents which change color when specific types of air contaminants are introduced.

The length of the color change or stain, or the intensity of color change as compared to a comparative standard indicates the amount of material present.”

WHAT IS A DETECTOR TUBE?


• Glass Vial (120 x 7 mm)

• Filled with a chemical reagent (s)

• Air is pulled through with a hand operated pump

• The reagents change color if the targeted chemical is present

WHAT IS A DETECTOR TUBE?


• More than 200 Draeger-Tubes

• Detecting more than 500 substances

• Measurements in air, liquids, and soil

• Gases (CO, H2S, Cl2,…)

• Vapors (acetone, benzene, ethyl alcohol,…)

DRAEGER-TUBES


• Adequate lighting - but no direct sunlight• Hold the tube against a light background• Scale tubes:

a) full length of discoloration(sum of all colors)

b) diffuse indication(end point of the slightest discoloration)

• Compare with an unused tube• Diagonal leading edge:

average between the shortest andlongest discoloration

READING DRAEGER-TUBES


• Operating Instructions

• Draeger-Tube Handbook

• VOICE Software

MUST be verified by Draeger, DO NOT assume that the measuring range is linear for all sample volumes!

EXTENDING THE MEASUREMENT RANGE


Conversion of semantics:

ppm = ml/m³ mg/m³

C [ppm] = c [mg/m³] x 24.1 *)

Molar mass [g]

C [mg/m³] = c [ppm] x Molar mass [g]

24.1 *)

*) 24.1 L Mole volume at 20°C and 1013 hPa

MEASUREMENT OF GASESBASICS


ppm = parts per million ml/m3 or l / 1 miol.

Vol.% = Liters of Contaminant100 Liters of Air

1 Vol.% = 10,000 ppm

ppm = mg x 24m3 x MW (at 20 °C, 68 °F)

MW=>molecular weight (g/mole) & 24 => mole volume (moles/L)

UNITS OF MEASUREMENT


Draeger-Tubes (7 mm)

• Less Cross-Sensitivity• Shorter Testing Time...

e.g. NH3 5-70 ppm, 1 minute• More Distinct Length of Stain...

e.g. CO 2-60 ppm, 25 mm @ TLV

• Longer Shelf-Life (2 Years)• No Cold Storage Requirement...

0 to 25 °C (0 to 77 °F)• Advanced Tube Designs• Quality Control Batch Testing• ISO 9001 Certification • Detecting >500 substances

DRAEGER TUBE ADVANTAGES

5 mm Tubes

• Higher Cross-Sensitivity• Longer Testing Time

e.g. NH3 10-50 ppm, 3.5 minutes• Shorter Length of Stain

e.g. CO 5-50 ppm, 11 mm @ TLV• Ambiguous Shelf-Life• Cool Storage Requirement

0 to 15 °C (0 to 50 °F)require Pyrolyzer

• Batch Testing• ISO 9001 Certification


Ü Draeger detector tubes and gas detection pumps are designed and calibrated as a unit.

Ü Interchanging Draeger pumps and tubes with other manufacturer’s products is not recommended nor permitted according to official regulations (e.g. ANSI / ISEA 102-1990, R 1998 or EN 1231)

DRAEGER ACCURO PUMP


• Insert unopened Draeger detector tube into socket.

• Squeeze pump completely and release.

• Pump is adequately leak proof if the end-of-strokeindicator has not appeared (popped up) after 15minutes.

• if the end-of-stroke indicator appears within 15 minutes:

1. Clean the exhaust valve and valve seating area2. Replace the exhaust valve3. Replace the socket
