AERASGARD KCO2 - SD / KCO2 -W
Patented quality product (patent no. DE 10 2014 010 719.1)
Maintenance-free duct sensor AERASGARD
on lid, 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 duct sensor AERASGARD
enclosure with quick-locking screws, optionally with/without display, 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. One sensor for every 30 m² of
space is recommended.
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.
