This is the user guide for Rotronic AG's HygroFlex HF5 Humidity Temperature Transmitters.
This manual provides instructions for the Rotronic HygroFlex HF5 transmitter series, designed for fixed installation where high measurement accuracy is required. The HF5 series features interchangeable HygroClip 2 plug-in probes and supports various output configurations, including analog, digital, and combined outputs. It allows for the calculation of psychrometric parameters such as dew point, frost point, and enthalpy using HW4 software.
