The HygroFlex1 series is the latest development in inexpensive HVAC transmitters for relative humidity and temperature. The devices are equipped with the tried-and-tested Hygromer® IN-1 sensor and boast unbeatable value for money. The optional ROTRONIC SW21 software enables you to scale, calibrate and adjust (only humidity) the transmitter.
