EGQ222F931
Maintenance-free room sensor with active output, automatic calibration, in an elegant plastic housing with snap-on lid, for determining the CO2
content of the air (0...2000 ppm) and the temperature (0...+50°C). The measuring transducer converts the measured values into a standard signal
of 0 -10 V.
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. One sensor for every 30 m² of
space is recommended.
A digital temperature sensor guarantees exact measurement results. 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.
