Wall mount – CO2 and temperature transmitter

Johnson Controls offers a Carbon Dioxide (CO2) and temperature wall mount transmitter for measuring the CO2 levels and the relevant temperature. Optional with humidity measurment (CD-3xx-E00-00).

Typical applications are schools, office buildings, hotels, cinemas or similar. This new CO2 transmitter is easy to install and requires no maintenance or field calibration.

The CD-cxx Series incorporates a single beam dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly. The SCD Transmitter is available with up to 3 x 0-10V outputs (CO2, Temperature and relative humidity).
