Natural Gas Test Detection Tubes - Qualitative
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

||a) CH4 + KMnO4 + H2S2O7 ──> CO
b) CO + I2SO5 ──> I2 + CO2
||Due to the reaction principle a number of other organic compounds such as propane and butane are indicated as well. Carbon monoxide is also indicated. It is not possible to differentiate between different compounds.
