Hydrogen Detection Tubes 0.2%/a (0.2 - 2 Vol.%)
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

0.1 Vol. % acetylene
6 Vol. % alcohol
6 Vol. % ammonia
0.5 Vol. % carbon monoxide
||The indicating layer is heated up by hydrogen concentrations of more than 10 vol. %. The air sample must not contain additional flammable substances whose ignition temperature is below 250 °C/ 482 °F as this will cause an explosion risk.
