The maintenance-free microprocessor-controlled AERASGARD® RFTM - LQ - CO2 and RCO2 - W is used to monitor the entire room climate. In order to do this, the measurands air humidity, temperature, CO2 concentration as well as air quality (VOC) are measured. All parameters are converted to standard signals (0 -10 V or 4...20 mA). As an option, a measurand can be shown continuously in the illuminated display. By measuring all four measurands in one device, it is possible to monitor and control the entire indoor climate effectively. The RFTM-LQ-CO2 and RCO2-W measures CO2 in the range from 0...2000 ppm or 0...5000 ppm, VOC in one of three selectable sensitivity levels LOW/ MEDIUM (default)/ HIGH, temperatures in the range from 0...+50°C as well as the relative air humidity of 0...100 % Elegant housing made of plastic, with snap-on lid, base with 4-hole attachment, for fitting to vertically or horizontally installed flush-mounted boxes, with predetermined breaking point for surface-mounted connection. Relative humidity (% r.H.) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. A digital, long-term stable sensor as a measuring element for relative humidity and temperature guarantees exact measurement results. The air quality is determined based on a (VOC) mixed gas sensor. The CO2 content of the air is determined by means of optical NDIR sensors (non-dispersive infra-red technology).
