Multicomponent gas analysers are automatic portable instruments of continuous operation.
The field of application of gas analysers is control of industrial emissions.
The principle of operation of gas analysers:
- on measurement channels O2, CO, NO, NO2, SO2, H2S, NH3 - electrochemical;
- on measurement channels of CO (0-15 %), CO2 and CH - optical infrared;
- on the channel of gas flow temperature measurements - thermoelectric;
- for differential pressure measurement channels - strain-resistive transducer.
Structurally, the gas analysers are single-unit devices made in durable plastic cases. The devices, apart from the gas analyser itself, include devices for sampling and sample preparation for analysis.
