RCO2.T.RH.x U/OC – RLQ.T.RH U/OC

Multi-function room CO2 and/or air quality sensor with active. Output

Application
The RCO2.T.RH.x or RLQ .T.RH determines the CO2 content, temperature, air quality and relative humidity in the room air, depending on the variant of the unit. The air quality is determined on the basis of a mixed gas sensor/ VOC sensor (volatile organic compounds). The CO2 content of the air is determined by means of an NDIR sensor. A self-calibration of the CO2 measurement is carried out every 7 days. To ensure this function, the unit must be supplied with fresh air (CO2 content approx. 350 ppm) at least once within a period of 7 days.
