Draeger Tube Polytest CH28401

The Draeger Tube Polytest CH28401 is high precision. The Dräger sampling tubes and systems provide very reliable results, even with complex compounds and mixtures of substances.

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 → 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 → I2 + CO2

 

Cross Sensitivity

Based on the reaction principle, the tube indicates many easily oxidized compounds, 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

 

The tube does not indicate methane, ethane, hydrogen and carbon dioxide.

Additional Information

If there is no reading, this does not always indicate that easily oxidizable substances are not present. In the individual case, quantify the use of Dräger Polytest by independent methods, particularly when combustible gases and vapors close to the LEL, or you suspect toxic substances.

Accurate and reliable results

Draeger-Tubes with the Accuro Pump deliver the most accurate results. 60+ years of manufacturing colorimetric tubes. The bellows pump design delivers consistent volume. Individual calibration of each batch of Draeger gas detection tubes Polytest included, accomplishes quality assurance. Every batch undergoes testing at regular intervals, throughout the two year shelf life, to guarantee accuracy over the entire life of the tubes.

Draeger Polytest Detector Tubes

Collect the hazardous substances in the air by using a suitable medium such as activated carbon, silica gel, or molecular sieves. Then analyze the sample in a laboratory with the aid of instrumental analysis.

Suitable for Complex Cases

Draeger sampling tubes and systems allow identification and measurement of different substances even under difficult conditions. Use Draeger Tubes to simultaneously and accurately measure very complex mixtures of substances or cases in which several similar substances are present. Dräger Tube Polytest has the Draeger SKU CH28401.

Dräger accuro

Fast measurement with one hand: The Dräger-Tube pump accuro allows you to use the established Dräger-Tubes to take measurements under extreme conditions. The easy to use Draeger Tube CH28401 Polytest has already undergone calibration. It forms a perfect unit with the Dräger-Tube pump including the Draeger Safety Polytest Tube.
