Rotronic Hygro Flex 5 Transmitters for Humidity and Temperature
The new HygroFlex5-series is the latest development in transmitters for humidity, temperature and dew point. One outstanding feature of this innovative product is, the possibility to output all psychrometric calculations as an analog signal.
The HF5-series is compatible with HygroClip2 probes with integrated AirChip3000 technology – thanks to which the probes achieve a degree of accuracy not seen before. In combination with advances in sensor technology and integration, the HygroFlex HF52-, HF53- and HF55- transmitters provide superb precision and state-of-the-art functionality, taking humidity, temperature and dew point measurements to a whole new level of performance (< 0.02 %rh) and reliability (< 0.8 %rh and < 0.1 K).
