CO2-K
Duct mount CO2 transmitter
The duct air quality sensor CO2-K/A measures the CO2 concentration of the ambient air in the range of
0-10000 ppm and optional the air temperature from 0…+50°C.
The transducer converts the measurement values for further processing in a linear output signal 0-10 V.
The CO2 is measured by a non-dispersive infrared sensor (NDIR), which operates on the 2-beam
measuring principle, to compensate pollutions, drifts etc. of the sensor.
The zero-point adjustment in response to the current environmental conditions can be made by manual calibration on the device.
The air quality sensor runs in regular intervals an automatic re-calibration procedure, whereby a longterm stable CO2 measurement is ensured.
