Ethylene Glycol Detection Tubes (10 - 180 mg/m3)
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, e.g.: Determining and measuring concentration peaks, Measuring personal exposure in the inhalation area, Detecting leaks in pipelines, gas installations etc., and Air analysis in sewers, shafts and confined spaces.

It is impossible to measure ethylene
glycol in the presence of formaldehyde
and ethylene oxide because they produce
the same discoloration.
