Rotronic’s new HygroFlex1 series is the latest development in inexpensive HVAC transmitters for relative humidity and temperature, says the company. It’s equipped with the Hygromer® IN-1 humidity sensor and two freely scalable analog voltage or current outputs. The optional HW4 software enables you to change the scale and calibrate and adjust the transmitter.
