The HF4 transmitter series is designed for fixed installation in HVAC and light industrial applications where a high measurement accuracy is required within the range of 0 to 100 %RH and -50 to 100°C (-58 to 212°F). The key features of the HF4 will satisfy application requirements ranging from the most basic to demanding.

The HF4 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 HF4 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 HF4 will let you have it your way.
