J. DITTRICH
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
Ambient temperature -10 to +50° C.
Output 4-20 mA.
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.
