The Rotronic HF55 measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F), depending on the probe.
The HF55 is designed for fixed installation in HVAC and industrial applications. The HF55 transmitter is compatible with HygroClip2 probes with incorporated AirChip3000 technology. The HC2 (HygroClip2) probe achieves an unparalleled degree of accuracy that has never been seen before. With the combination of advances in sensor technology and integration, the HygroFlex HF52, HF53, HF54, HF55 and HF56 transmitters combined with a HC2-S probe provide superb precision and state-of-the-art functionality.
