COMPARISON ELECTRODE DEGRADATION DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a detector for conveniently determining a degradation in a comparison electrode without a polarization when a DC current flows.

SOLUTION: The detector is composed so as to flow the DC current between the evaluation target comparison electrode 12 and the comparison electrode 13 for presenting a reference potential in order to measure a resistance of a liquid contact section in the evaluation target comparison electrode 12 and determine the degree of a contamination of the liquid contact section from the resistance.
