CF1 Series CO2 measurement transducers

New product
 
More info

The CF1 series is the latest development in quality performance CO2 measurement transducers with integrated humidity and temperature measurement. The unit has the proven Hygromer® IN1 sensor, and an unrivaled performance. Its elegant design fits in perfectly in offices, schools, public buildings, etc. With the Rotronic SW21/HW4 software, altering the scaling is a simple matter, and the measurement transducer can be adjusted and calibrated in the humidity and CO2 ranges.
