Hygroflex5 – HF5 – HVAC – Transmitter


The HF5-series is the latest development in measurement transmitters for humidity, temperature and dewpoint. The HF5-series is compatible with HygroClip2 series probes with integrated AirChip3000 technology – thanks to which the probes achieve an unparalleled degree of accuracy not seen before. HygroFlex HF52, HF53, HF54 and HF56 transmitters combined with a HC2A-S advanced probe provide superb precision and state-of-the-art functionality, taking humidity and temperature measurement to a whole new level of accuracy < 0.8 %rh and < 0.1 K at 10…30 °C. One outstanding feature of this measurement device is the possibility to output any psychrometric calculation as an analogue or digital signal.
