CF1 - Measurement Transmitter for CO2, Humidity and Temperature

The CF1 series is the latest development in reasonably-priced CO2 measurement transducers with integrated humidity and temperature measurement. The unit has the proven Hygromer® IN1 sensor, and an unrivalled price-performance ratio. Its elegant design fits in perfectly in offices, living-rooms, 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.
