Ethylene Oxide Detection Tubes 1/a (1 -30 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 vapours 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.

quinoid reaction products
||Styrene, vinyl acetate and acetaldehyde are indicated with a yellowish brown discoloration.
It is impossible to measure ethylene oxide in the presence of ethylene glycol and formaldehyde because they produce the same discoloration.
||The reagent ampoule must be broken before carrying out the measurement.
