The HF4 transmitter measures temperature, relative humidity and the dew or frost point. The HF4 series is designed for fixed installation in HVAC and light industrial applications where a high measurement accuracy is required at conditions within the range of 0 to 100 %RH and -50 to 100 °C (-58 to 212 °F). The electronics operating range is limited to -40…60 °C (-10…60 °C with the optional LC display).
The HF4 features well proven sensors and a robust housing. Digital signal processing ensures consistent product performance and also facilitates the task of field maintenance with features such as potentiometer free – digital calibration.
