J. Dittrich Elektronic gas measuring systems for toxic gases and vapors determine the concentration of toxic gases and vapors in the air mixture at an ambient temperature of -10 to +50° C.
Specific electrochemical sensors measure ammonia (NH3), chlorine (Cl2), carbon monoxide (CO), oxygen (O2), hydrogen sulphide (H2S), nitrogen dioxide (NO2) and nitrogen monoxide (NO) in the ppm range.
The sensors are calibrated with the help of the respective test gas using a potentiometer; there is no or only negligible cross-sensitivity to other substances.
