<P>PROBLEM TO BE SOLVED: To provide an electrode structure of a standard electrode for measuring self-potential with which the self-potential of thin tubes in a heat exchanger can be measured as accurate as possible. <P>SOLUTION: An electrode structure of a standard electrode Ps for measuring self-potential, in a heat exchanger HE provided with plural metal thin tubes 2 through which a heating medium M flows, comprises an insertion body 11 for measuring potential inside the thin tube. The insertion body 11 is inserted in the thin tube 2 in a state in which one end portion thereof is arranged inside the thin tube 2 and the other end portion thereof is arranged outside of the heat exchanger HE. The insertion body 11 is configured by forming a housing body having an insulation property in a cylindrical shape, and filling the housing body with an electrolyte material. The electrolyte material has flowability to electrically connect the heating medium M inside the thin tube 2, at which the one end portion of the insertion body 11 is arranged, and an electrolyte solution 10 into which a metal body for electrode 9 in the standard electrode is immersed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
