CO2 monitors - carbon dioxide transmitters


CO2 monitor

CO2 monitor

CO2 sensor. The CO2 - carbon dioxide level is recently regarded as an important parameter that substantially determines the quality of the interior climate. Especially in buildings where many people gather, such schools, meeting rooms, hospitals, cinemas, theatres and care centers. With the help of environmental experts and health specialists can optimize the ventilation for creation of a healthy interior climate.
The CO2 measurement is based on a 2-source, 2-beam process. CO2 measurement with long-term stability is guaranteed thanks to the proven non-dispersive infrared (NDIR) CO2 measurement cell. The unique patented auto-calibration procedure compensates for aging of the infrared source and guarantees high reliability, long term stability and eliminates the need of periodical recalibration in the field.
