Maintenance-free room sensor AERASGARD® RCO2 - SD with active output, automatic calibration
(fixed), in an elegant plastic housing with snap-on lid, for determining the CO2 content of the air
(0...2000 ppm). The measuring transducer converts the measured values into a standard signal
of 0 -10 V.
Maintenance-free room sensor AERASGARD® RCO2 - W with active/switching output, automatic
calibration (can be deactivated), in an elegant plastic housing with snap-on lid, optional with traffic light
indicator (five coloured LEDs), 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 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.
