HygroFlex1 Series Humidity Transmitters
Inexpensive HVAC transmitters for relative humidity and temperature
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 HW4/SW21 software enables you to change the scale and calibrate and adjust the transmitter.
