AERASGARD RCO2 - AS NT
Maintenance-free room sensor AERASGARD
housing, for determining the CO2 content of the room air (0...3000 ppm). The measuring transducer converts the measurand to a standard signal,
which is directly presented visually via coloured LEDs (traffic light indicator). An additional signal tone sounds when the warning levels are reached
(can be switched off via DIP switch).
Available as a table-top unit RCO2-AS NT ST with micro USB power cord and stainless steel stand holder, as well as the device versions
RCO2-AS NT (with plug-in power supply unit), RCO2-AS UPNT (with in-wall power supply unit) and RCO2-AS (without power supply unit) for wall
mounting.
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 demand-based room ventilation, thereby reducing operating
costs and improving well-being. We recommend one sensor for every 30 m² of space. The CO2 measurement is performed using an optical NDIR
sensor (non-dispersive infra-red technology).
