Dräger Tube Phosgene 0.25/c - PN: CH28301
Dräger Tube Phosgene 0.25/c (10)
PN: CH28301
Dräger-Tubes™ are used together with a Dräger tube pump for measurements of gases, vapors and aerosols, usually in air, and are one of the classic methods of gas analysis. This Dräger-Tube is used for the detection of phosgene and has the following standard measuring ranges: 0.25-5 ppm 0.01-0.3 ppm Measurements: 10
Application Range
Standard Measuring Range: 0.25 to 5 ppm
Number of Strokes n: 5
Time for Measurement: approx. 1 min
Standard Deviation: ± 15 to 20 %
Color Change: yellow ä blue green
Ambient Operating Conditions
Temperature: 5 to 35 °C
Absolute Humidity: 3 to 15 mg H2O / L
Reaction Principle
COCI2 + ethylaniline + dimethylaminobenzaldehyde ä blue green reaction product
Cross Sensitivity
No interference by up to 100 ppm hydrochloric acid. Carbonyl bromide and acetyl chloride are indicated, but with different sensitivities. It is impossible to measure phosgene in the presence of carbonyl bromide or acetyl chloride.
