|
| |
|
|
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. |
Product Features
| • Duct mounting
• Monitors CO2 over range 0-2,000 ppm
• RH accuracy of 2.5%
| • Lifetime calibration interval of CO2
• Gas permeable PTFE filters on both sensors
• Optional thermistor output for temperature
