Insertion rh Probes

Models HC2-P05, HC2-HP28 and HC2-HP50

These insertion probes are designed for relative humidity measurement applications to monitor the humidity or moisture level inside dust-free materials like bricks or concrete. They are also used for water activity measurements in a variety of solid materials.
