Description
The HF7 HygroFlex7 series of relative humidity and temperature transmitters from ROTRONIC is designed for finite installation in industrial applications where conditions are in the range 0 … 100% RH and -100 … +150 °C.
The HF7 probe can survive exposure at temperatures up to 200 °C. The HF7 is equipped with a metal housing and a metal probe that works even in the harshest industrial environments.
The HF7 is available in a variety of configurations and has extensive settings and features that can be configured and enabled with the Rotronic HW4 software once the HF7 and PC are connected.
Derivatives
The HF7 series includes the HF720, HF732 and HF735. To help you choose your model, please refer to the datasheet in the Documentation tab.
