Trichloroethane Detection Tubes 50/d (50 - 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 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
|Standard Measuring Range:
||50 to 600 ppm
|Number of strokes n:
||2 + 3 desorption strokes in clean air
|Time for Measurement:
||approx. 1.5 min
||± 10 to 15 %
||gray ──> brown red
||15 to 40 °C
||5 to 15 mg HO / L
||a) 1,1,1-trichloroethane + IO3-/H2S2O7 ──> Cl2
b) Cl2+ o-tolidine ──> brown red reaction product
||Other chlorinated hydrocarbons are indicated, but with different sensitivities.
In the presence of aromatic hydrocarbons the indication is too low (e.g. 200 ppm 1,1,1-trichloroethane and 200 ppm toluene, the reading amounts to 1/4 only, i.e. 50 ppm).
