EGQ212F931
Maintenance-free duct sensor with active output, automatic calibration, in an impact-resistant plastic housing with quick-locking screws, for deter-
mining the CO2 content of the air (0...2000 ppm/0...5000 ppm) and the temperature (–35...+80 °C). The measuring transducer converts the meas-
ured 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.
