CO2 sensor for schools | CO2 traffic light AERASGARD® RCO2-AS
Maintenance-free AERASGARD® RCO2-AS xx CO2 detector with traffic-light indicator and acoustic signal, self-calibrating, in an attractive plastic 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 visualised by colour LEDs (traffic light indicator). An additional signal tone sounds when warning levels are reached (can be switched off via DIP switch).
