Chloroformates Detection Tubes 0.2/b (0.2 - 10 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

||Methyl, ethyl and isopropylchloroformate are indicated with approximately the same sensitivity. It is impossible to differentiate them. Petroleum hydrocarbons, aromatics, alcohols and ketones in the TLV range do not affect the indication. It is impossible to measure chloroformate in the presence of phosgene.
