Phosgene Detection Tubes 0.02/a (0.02 - 1 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
A wide range of different gases and vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
|Standard Measuring Range:
||0.02 to 1 ppm / 0.02 to 0.6 ppm
|Number of strokes n:
||20 / 40
|Time for Measurement:
||approx. 6 min / approx. 12 min
||± 10 to 15 %
||white ──> red
||0 to 40 °C
||3 to 15 mg H2O / L
||COCl2 + Aromatic amine ──> red reaction product
||Chlorine and hydrochloric acid lead to plus errors and, at higher concentrations, to bleaching of the indicating layer. Concentrations of phosgene above 30 ppm will also lead to bleaching of the indicating layer.
||High concentrations of phosgene will be not indicated!
