AX-GS-CDRHT-D / Duct Mounted CO2 and RH&T Sensor POA Qty

The AX-GS-CDRHT-D Duct Mounted CO2 and RH&T Transmitter uses NDIR single beam Infra-red technology to monitor CO2 concentration levels and output a corresponding 0-10V output. In addition the unit includes capacitive humidity and band gap temperature sensors. The unit is intended for use in return air ducts.
