The new HygroFlex4 series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. Based on AirChip3000 technology, these precision instruments achieve a new level of accuracy in this category of product, and are more precise than the HF3 series. The new generation boasts 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 HygroFlex4 series offers maximum reproducibility and a system accuracy of <±1 % rh and ±0.2 K. The transmitters are available in wall and duct mount versions. Many useful functions can be activated with the optional HW4 software.
