RCO2-W-Display Room CO2 sensor 0...2000 / 5000ppm, changeover contact (adjustable) & display, BALDUR II

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 colored 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 centers, 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 infrared technology). The detection range is calibrated for standard applications such as monitoring residential rooms and conference rooms.
