With AMUN CO2 sensors, CO2 traffic lights and mobile CO2 monitors from Theben, you can improve the air quality in public spaces such as schools, kindergartens, universities, meeting rooms or large offices. The CO2 content of the air is constantly monitored. If the adjustable threshold values are exceeded, the device warns via an LED traffic light system and switches on the ventilation control or climate control. In addition, devices with integrated measurement of temperature and relative humidity for optimized fan control are available.
