CDT-2000/5000 series Carbon Dioxide CO2 Transmitters

CDT-2000/5000 series

Our CDT-2000/5000 carbon dioxide transmitter is designed for measuring CO2 in indoor environments.

The CDT-2000/5000 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 CDT-2000/5000 is available with an additional sensor for measuring temperature and humidity.
