ABSTRACT:
A colorimetric detector such as a gas dosimeter, contains a strip-like carrier with a detection reagent in a transparent housing that can be opened at least at one end thereof. The detector is expanded in terms of its use to such reagent systems in which the pigment formed diffuses beyond the reaction zone. For this purpose, the detection reagent is provided such that it is contained in impregnated tabs arranged in a row on the carrier.
