Product Description
CGESC02xxW type set new standards in CO2 measurements for HVAC.
The transmitters resp. switches combine CO2, relative humidity (RH) and temperature (T) measurement inone modern and userfriendly housing.
The basic CGESC02TW version for CO2and T can be easily extendedwithaRH plug-in module.
The CO2 measerument is based on the infrared principle. A patented auto-calibration procedurecompensatesfor
the aging of the infrared source and ensures outstanding long term stability.
This sensor provides analogue outputs (in V or mA). The optional display indicates sequentially the actual measuring data.
As one more option a switching output with adjustable switching point and hysteresis is available.
A wide variety of models ensures an optimal adjustment for customised requirements.
