The HygroFlex series is a state-of-the-art development in HVAC transmitters for relative humidity, temperature and dew point. Mostly based on AirChip3000 technology, the transmitters offer high accuracy at a low cost. They boast a unique calibration and adjustment process as well as many other unbeatable innovations. At the same time, we have taken the sensor technology to a whole new level of performance and reliability: The HygroFlex series offers you maximum reproducibility and a guaranteed system accuracy of up to <±0.8 %rh and ±0.1 K. The transmitters come in various versions and there are also thermostats/hygrostats available for the duct and wall versions. Many useful functions can be activated with the optional HW4 software.
