The HF5 transmitter is designed for fixed installation in either HVAC or industrial applications. The key features of the HF5 will satisfy application requirements ranging from the most basic to demanding. Selecting the appropriate probe model from the HF5 probe options is done based on the application. Depending on the probe model, the measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F). The HygroClip 2 probes feature durable sensors and consistent performance. All HygroClip 2 probes can be hot-swapped 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 by the user with the ROTRONIC HW4 software.

In spite of its sophistication, the HF5 can still be used just as a simple conventional humidity and temperature transmitter. Whether you decide or not to take advantage of its full potential, the HF5 will let you have it your way.
