Description
Room humidity, temperature, air quality and CO2 sensor
AERASGARD® RFTM-CO2 / RFTM-LQ-CO2
Maintenance-free room sensor AERASGARD® RTM - CO2 - SD with active output, automatic calibration (fixed), in an elegant plastic housing with snap-on cover, for determining the CO2 content of the air (0...2000 ppm) and the temperature (0...+50°C). The measuring transducer converts the measured values into a standard signal of 0-10 V.
The air quality is detected by a VOC sensor (mixed gas sensor for volatile organic substances). This sensor determines the load of contaminated gases in the room air, such as from cigarette smoke, body perspiration, exhaled breathing air, solvent vapours, emissions from building components, etc. Low, medium or high VOC sensitivity can be selected depending on the expected air contamination.
