AERASGARD RCO
Maintenance-free AERASGARD
elegant plastic housing, for determining the CO
standard signal, which is directly presented visually by five coloured LEDs (traffic light indicator). Available in device versions RCO
wall mounting, RCO -A UPNT for mounting on in-wall flush boxes and RCO

The room sensor 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 im-
proving well-being. The CO measurement is performed using an optical NDIR sensor (non-dispersive infra-red technology).
