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.
Design
The housing is made of aluminium and suitable for wall mounting.
The measured values are output via a linear current output (4-20 mA),
and then they are evaluated and processed further in a device arranged downstream by the user.
The appropriate sensor is installed according to the gas or vapor that is to be measured.
