Air Quality Transmitters measure CO2, RH, and temperature.
Electrical Equipment & Systems

Air Quality Transmitters measure CO2, RH, and temperature.

Combining CO2, RH, and temperature in one device, Series CDTR minimizes number of sensors mounted on wall or in duct. Transmitters use single-beam, dual-wavelength NDIR sensor to automatically correct measurement in both occupied and unoccupied buildings against light source aging effects. Universal outputs for both carbon dioxide and relative humidity allow users to select transmitter output to...
