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
Standard Deviation: ± 10 to 15 %
Color Change: gray ──> brown red
Temperature: 15 to 40 °C
Absolute Humidity: 5 to 15 mg HO / L
Reaction Principle: a) 1,1,1-trichloroethane + IO3-/H2S2O7 ──> Cl2
b) Cl2+ o-tolidine ──> brown red reaction product
Cross Sensitivity: 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).
