The QPA Series Room Carbon Dioxide Sensors monitor and transmit changes in CO2 to the building control systems. No calibration of the CO2 sensor is necessary, these microprocessor-based units consist of a nondispersive infrared CO2 sensor that experiences less than 1% drift per year for the first two years of operation and negligible drift thereafter. All variants for CO2 and combination versions with Temperature or VOC deliver0 to 10 Volt or 0 to 5 Volt (field selectable) proportional signals to the controller.
These units are especially suited for applications where precise, stable CO2 sensing is required
