Abstract
A system for measuring the potential between a working electrode in a pressurized, high temperature environment containing a solution which supports electrolytic conduction and a reference electrode is disclosed herein. This system utilizes an external reference electrode assembly which includes a particular technique of balancing its own internal pressure with the pressure in the high temperature environment in order to eliminate streaming potentials between the working electrode and the reference electrode. This assembly also includes a technique for maintaining the concentration of electrolytic solution at a substantially fixed and uniform level so as to maintain a fixed thermal liquid junction.
