Dräger Tube Polytest - PN: CH28401
Dräger Tube Polytest (10)
PN: CH28401
Application Range
Standard Measuring Range: Qualitative determination of easily oxidable substances
Number of Strokes n: 5
Time for Measurement: approx. 1.5 min
Color Change: white ä brown, green or violet (depending on substance)
Ambient Operating Conditions
Temperature: 0 to 50 °C
Absolute Humidity: max. 50 mg H2O / L
Reaction Principle
CO + I2O5 ä I 2 + CO2
Cross Sensitivity
Based on the reaction principle, many easily oxidised compounds are indicated, several examples are shown below:
2000 ppm acetone 10 ppm acetylene
50 ppm ethylene 1 ppm arsine
10 ppm octane 50 ppm benzene
500 ppm propane 100 ppm butane
5 ppm carbon monoxide 10 ppm styrene
1 ppm carbon disulfide 20 ppm perchloroethylene
2 ppm hydrogen sulfide 10 ppm toluene, Xylene Methane, ethane, hydrogen and carbon dioxide are not indicated.
Additional Information
If there is no reading, this does not always indicate that easily oxidizable substances are not present. In the individual case, the use of Dräger Polytest should be qualified by independent methods, particularly when combustible gases and vapors close to the LEL, or toxic substances are suspected.
