描述
- GMCD CO2 transmitter is designed to measure CO2 level in the duct system.
- It is extensively used in HVAC applications to implement ventilation strategy.
- The NDIR sensing technology with self calibration and built-in temperature compensation features ensure high accuracy in long term.
- Standard signal outputs are provided to facilitate integration into indus- trial controllers.
- CO2 gas detection sensors can monitor doors, wind tunnels, the concentration of CO2 gas, suitable for indoor, duct installation, gas monitoring that can be widely used in the built environment
