CDT-2000/5000-Duct Carbon Dioxide CO2 Transmitters for Duct
Our CDT-2000/5000-Duct is designed for measuring CO2 in air ducts of ventilation systems.
The CDT-2000/5000-Duct converts the the values measured in the ranges of optionally 0-2000 ppm or 0-5000 ppm into 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-duct is available with an additional sensor for measuring temperature and humidity.
