AERASGARD RCO2 - AS NT
Maintenance-free room sensor AERASGARD
in an elegant plastic housing, for determining the CO2 content of the air in the room (0...3000 ppm). The measuring transducer converts
the measurand to a standard signal, which is directly presented visually by five coloured LEDs (traffic light indicator). An additional acoustic
signal sounds when the next warning level is reached (can be switched off via DIP switch). Available in device version RCO2-AS NT ST with
metal stand for flexible positioning.
The room filter with CO2 traffic light is used in classrooms, training rooms and convention centres, offices, hotels, apartments, shops, etc.
and is used for easy and quick evaluation of the indoor climate. This enables energy-saving room ventilation on an as-needed basis,
thereby reducing operating costs and improving well-being. We recommend one sensor for every 30 m² of space.
The CO2 content is measured with an optical NDIR sensor (non-dispersive infra-red technology).
