ABSTRACT:
A reference electrode for use in testing liquid at a high pressure, has an internal liquid containing body having an internal liquid containing space therein and a liquid-junction one side of which is exposed to the high pressure liquid to be tested and the other side of which is exposed to the internal liquid contained in the internal liquid containing space. A reference electrode body surrounds the internal liquid containing body and defines a pressure compensating space between the internal liquid containing body and the inside of the reference electrode body, the pressure compensating space being open outwardly of the reference electrode body at a part there of which is exposed to the high pressure liquid to be tested when the reference electrode is in position for normal use, the pressure compensating space receiving the high pressure liquid to be tested therein. A flexible bellows is provided between the spaces and in liquid tight engagement with the internal liquid containing body for compensating for the pressure of the high pressure liquid to be tested on the internal liquid through the liquid-junction.
