The maintenance-free microprocessor-controlled room sensor AERASGARD® RCO2 - SD with automatic calibration (fixed) is used for recording the CO2 content of the air within a range of 0...2000 ppm. The measurement value is converted into standard signal of 0 -10 V.
The maintenance-free microprocessor-controlled room sensor AERASGARD® RCO2 - W with automatic calibration (can be deactivated via DIP switches) is used for detecting the CO2 content of the air within a range of 0...2000 ppm or 0...5000 ppm. The measurement value is converted into standard signal of 0 -10 V or 4...20 mA. Optional with traffic light indicator (five coloured LEDs).
Elegant enclosure made of plastic, with snap-on lid, based with 4-hole attachment, for installation on vertically or horizontally installed flush-mounted boxes, with predetermined breaking point for surfacemounted connection or in enclosure made of stainless steel (top and bottom parts are stainless steel, the cover is screwed on), vandal-proof version e.g. for schools, barracks and public buildings.
The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range of the CO2 sensor is calibrated for standard applications such as monitoring residential rooms and conference rooms. Room ventilation on an as-needed basis, improved well-being and customer benefit, increased comfort as well as reduced operating costs through energy conservation.
