Potential Meters

Potential meters are basically electrometers which have extremely high input resistances in order to keep the feeding reference electrode free of load. This is necessary to maintain the true potential. pH - meters can be used as potential meters when fast reading is not required, because common pH meters are very slow. When the potential answer to current pulses is to be followed, potential meters are essential.
