CO2 monitor, carbon dioxide sensor | Temperature Humidity Transmitters

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. CO₂measurement 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.
