Maintenance-free AERASGARD® ACO2-SD on-wall air quality measuring transducer with active output, automatic calibration (fixed), in an impact resistant plastic housing with quick-locking screws, for determining the CO2 content of the air (0…2000 ppm/0...5000 ppm). The transmitter converts the measured values into a standard signal of 0-10 V.
Maintenance-free AERASGARD® ACO2-W on-wall air quality measuring transducer with active/switching output, automatic calibration (can be deactivated), in an impact resistant plastic housing with quick-locking screws, optionally with/without display, for determining the CO2 content of the air (0…2000 ppm/0...5000 ppm). The transmitter converts the measured values into a standard signal of 0-10 V or 4...20 mA (switchable).
The sensor devices are used in offices, hotels, convention centres, apartments, shops, etc. for the purpose of evaluating the indoor climate. This enables energy-saving room ventilation on an as-needed basis, thereby reducing operating costs and improving well-being.
The CO2 content is measured using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as the monitoring of residential and conference rooms.
