HF5 Humidity Temperature Transmitter

The HF5 transmitter is designed for fixed installation in HVAC and industrial applications, and provides two analog outputs or a digital output signal corresponding to relative humidity, temperature, dew point or another psychrometric parameter. The HF5 uses a plug-in HygroClip 2 probe, the model of probe being determined by the application. The measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F), depending on the probe. All HygroClip 2 probes feature durable sensors, consistent performance and can be hot-swapped at any time to facilitate routine calibrations.

The HF5 transmitter is available in different configurations and has an extensive set of settings and functions that can be configured and enabled with the ROTRONIC HW4 software after connecting the HF5 to a PC.
