Our KACO2 records the ambient air's CO2 concentration in air ducts of air-conditioning systems. The KACO2 converts the the values measured in the ranges of optionally 0-2000 ppm or 0-5000 ppm into a linear 0-10 V output signal. The CO2 value is measured via the NDIR sensor, which is able to compensate possible pollution with the help of its 2-ray measuring principle. Optionally, our KACO2 is available with an additional sensor for measuring temperature and humidity.
