Siemens QPA Series Room Carbon Dioxide Sensor

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 deliver 0 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.

Features:

LCD display option
Various models: CO2; CO2/VOC; CO2/Temp; CO2/Temp/RH
Built-in test function for troubleshooting
Jumper selectable °C/°F units for temp models w/display
No Logo versions available
