Hygroclip 2 Standard Humidity probe


Ultra-stable, accurate and versatile probe for temperatures -50…100 °C



The standard Rotronic Humidity and Temperature probes can be used in application with temperatures from -50…100 °C / 0…100 %RH. With an outstanding accuracy of ± 0.8 %RH / ± 0.1°C. For calibration purposes the probes can be replaced without almost any downtime. Together with a Rotronic HF5, PF4/5 transmitter or HP32 the HC2A-S(H) probe is the first selection for many applications.

The HC2A-S(H) are the most sold versatile probe from Rotronic and form the basis of the product portfolio. They measure Humidity and Temperature and can calculate the dew-/ frost point.
