EAN 4 251325 613260

The maintenance-free microprocessor-controlled room sensor AERASGARD® RLQ-CO2-W with automatic and manual calibration is used for detecting the overall room climate. It measures CO2 within a range of 0...2000 ppm or 0...5000 ppm, air quality (VOC) in one of three sensitivity levels that can be selected LOW  /  MEDIUM (default)  /  HIGH, temperature within a range of 0...+50°C as well as relative ambient humidity of 0...100 %  r.H. The measured values are converted into standard signals of 0 -10 V oder 4...20 mA ( selectable via DIP switches). As an option, the measured values can be shown continuously in the illuminated display.

Elegant enclosure 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). For
