These CO2 switches provide a stable, secure environment with high performance. The switch is dependable, accurate and 100 % compatible with most building control systems. The CO2 room switch measures the concentration of CO2 from 0 to 2000 ppm in air using a NDIR sensor which is self-calibrating and maintenance-free in a normal environment.
The carbondioxide level is a parameter that determines the quality of the interior climate. The CO2 level is in fact a good benchmark for the level of ventilation in a room.
