ELECTRODE OF RESISTIVITY METER

摘要

PROBLEM TO BE SOLVED: To provide the electrode of a resistivity meter capable of simplifying the connection structure of an electrode member and an electric wire to suppress an increase in cost. SOLUTION: The electrode of a resistivity meter is equipped with an outer electrode, a support part, a second stop ring 20 and an outer electrode lead wire 7. The outer electrode is formed into a round pipe shape. The support part is equipped with the outer electrode holder fixed to the base end of the outer electrode and the outer electrode holder is formed into a round pipe shape. The second stop ring 20 is equipped with a member body 20a and locking pawl parts 20b and the member body 20a is formed into an annular shape and the locking pawl parts 20b are projected outwardly from the outer edge of the member body 20a and engaged with the inner peripheral surface of the outer electrode holder. The outer electrode lead wire 7 is connected to the member body 20a to be electrically connected to the second stop ring 20. When the locking pawl parts 20b of the second stop ring 20 are locked with the inner peripheral surface of the outer electrode holder, the outer electrode lead wire 7 is electrically connected to the outer electrode.
