Ethyl Benzene Detection Tubes 30/a (30 - 600 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, 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.
Contains 10 tubes
|Standard Measuring Range||30 to 400 ppm|
|Number of Strokes (n)||6|
|Time for Measurement||approx. 2 min.|
|Standard Deviation||±10 to 15%|
|Colour Change||white ─> brown|
|Temperature||10 to 30° C|
|Absolute Humidity||5 to 12 mg H2O / L|

|Cross Sensitivity||Many petroleum hydrocarbons and|
aromatics are indicated, but with
different sensitivities. It is impossible
to differentiate between them.
