AERASGARD® RTM-CO2-SD-UMaintenance-free room sensor AERASGARD® RTM - CO2 - SD with active output, automatic calibration (fixed), in an elegant plastic housing with snap-on cover, for determining the CO2 content of the air (0...2000 ppm) and the temperature (0...+50°C). The measuring transducer converts the measured values into a standard signal of 0-10 V.
