Cross Sensitivity

Other chlorinated hydrocarbons are also indicated, but with different sensitivities.

Perchloroethylene is indicated with a slightly higher sensitivity and 1,1,1-trichloroethane with about twice the sensitivity (e.g. 200 ppm x h 1,1,1-trichloroethane gives an indication of 400 ppm x h).

Chlorine and nitrogen dioxide in dosages higher than 10 ppm x h also discolor the indicating layer.
