The Rotronic HygroFlex5-series is the latest development in transmitters for humidity, temperature, and dew point. It features the ability to output all psychrometric calculations as analog signals. Compatible with HygroClip2 probes with integrated AirChip3000 technology, the HF5 series achieves exceptional precision and functionality.

AirChip3000 compensates humidity and temperature over 30,000 reference points, has a 2000-point data memory, calculates dew/frost point, and includes sensor auto-diagnostics and automatic correction. The transmitters are available as 2-wire (HF52), 3/4-wire (HF53), and digital (HF55) models, with optional backlit graphic display. Wall or duct mount versions are offered in ABS or aluminum housing.

Applications include food and pharmaceutical industries, printing and paper, meteorology, agriculture, and climatology. Accuracy is ±0.8%rh / 0.2K (probe dependent) with repeatability of 0.3%rh / 0.05°C, long-term stability <1%rh / <1°C per year, and response time τ63 <10 seconds.
