| Trichloroethane | 50 to 600 ppm |
Application Range:
| 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 % |
| Colour Change: | grey to brown red |
Ambient Operating Conditions:
| Temperature: | 15 to 40 °C |

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)..
