AERASGARD® RTM-CO2-SD-U

Item No. 1501-61B2-1001-200
EAN 4 251325 616377

The maintenance-free microprocessor-controlled room sensor AERASGARD® RTM - CO2 - SD with automatic calibration (fixed) is used for detecting the CO2 content of the air within a range of 0...2000 ppm and the temperature within a range of 0...+50°C. The measured values are converted into standard signals of 0 -10 V.

Elegant housing made of plastic, with snap-on lid, base with 4-hole attachment, for installation on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for on-wall cable entry. The relative humidity (% r.H.) quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. A digital, long-term stable sensor used as measuring element for relative air humidity and temperature guarantees exact measurement results. The air quality is determined based on a (VOC) gas mixture sensor. The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology).
