733663: CO2 Room Sensors | Active, 0..5 V, 0..10 V | 0..+50 °C

Room sensor for measuring CO2 content and additionally temperature and humidity (relative, absolute, enthalpy, dew point). The sensor is maintenance-free and ensures the control of comfort conditions in indoor environments. Typical applications are schools, offices, hotels, cinemas or similar buildings. VV and 3xV devices are available with additional LEDs for displaying CO2 levels (TLF - traffic light function); the LED color changes depending on the value measured by the sensor. The threshold values for normal status, pre-alarm and alarm can be easily set with the Thermokon NOVOSapp.
