Device is designed for detection, indication and control the CO2 in the air level in the interiors. The measuring of CO2 works on the principle of infrared radiation attenuation dependence on the CO2 concentration in the air. Unlike the other similar sensors working on the electrochemical principle it has very good long term stability.
