Phosphine Detection Tubes 0.1/b (in acetylene) (0.1 - 15 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
