Electrode description
FC10483 is a specially designed pH electrode intended for the direct determination of pH in wine
production; from freshly pressed juice all the way to the final fermented product.
The FC10483 pH probe features a refillable double junction reference electrode that uses a
KCI electrolyte, an open junction with Clogging Prevention System (CPSTM) technology, a built-in
temperature sensor for temperature compensated pH readings and an integrated preamplifier to
provide measurements impervious to noise and electrical interferences.
