Standard rh Probes

Models HC2-S and HC2-SH

The most versatile of the Rotronic's relative humidity and temperature probes is the HC2-S.  It forms the basis of the product portfolio.  The HC2-SH is the high-precision version, and this fulfils the highest demands on measuring accuracy.

Both of these probes can be used for HVAC, in the food industry, building services equipment, and paper, textiles and pharmaceuticals industries.
