ACO2-SD-U

AERASGARD® ACO2-SD-U

Item No. 1501-7110-1001-200
EAN 4 251325 616353

Maintenance-free on-wall sensor AERASGARD® ACO2-SD 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 measuring transducer converts the measured values into a standard signal of 0 -10 V.

Maintenance-free on-wall sensor AERASGARD® ACO2-W 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). he measuring transducer converts the measured values into a standard signal of 0 -10 V or 4...20 mA (switchable).

The sensor is 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 measurement is performed using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for standard applications such as monitoring residential rooms and conference rooms.
