The HF73A transmitter series is designed for fixed installation in industrial applications where conditions are within the range of 0 to 100 %rh and -100 to 150 °C (-148 to 302 °F). The probe of the HF73A can survive exposure to temperature up to 200 °C (392 °F). Equipped with an aluminum enclosure and a PPS probe, the HF73A can handle the toughest industrial environments.
 
The HF73A transmitter is available in different configurations and has extensive settings and functions that can be configured and enabled with the ROTRONIC HygroSoft software after connecting the HF73A to a PC.
