AERASGARD RCO2 - A NT
Maintenance-free AERASGARD
elegant plastic housing, for determining the CO2 content of room air (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). Available in device versions RCO2-A NT for direct
wall mounting, RCO2-A UPNT for recessed installation on flush-mounting socket and RCO2-A NT ST with metal stand for flexible positioning.
The room sensor is designed for use in class, seminar and meeting rooms, offices, hotels, homes, shops etc. and provides a simple and fast way of
assessing the room climate. This enables an energy saving and on-demand room ventilation, thus reducing the overall operating costs and enhancing
the well-being of occupants. One sensor for every 30 m² of space is recommended.
The CO2 content is measured with an optical NDIR sensor (non-dispersive infra-red technology).
