AERASGARD RCO
Maintenance-free room sensor AERASGARD
on lid, for determining the CO
signal of 0 -10 V.
Maintenance-free room sensor AERASGARD
plastic housing with snap-on lid, optional with traffic light indicator (five coloured LEDs), for determining the CO
(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 CO measurement is performed using an optical NDIR sensor (non-dispersive infra-red technology). The detection range is calibrated for
2
standard applications such as monitoring residential rooms and conference rooms.
