description PURPOSE:To measure polarization resistance by an iron electrode even during plant operation by fixing a reference electrode material which is covered with an insulating tube and securely insulated from small-diameter metal and an electrode material by an in-tube insulating filler so that the material is exposed from a small hole. CONSTITUTION:An electric feeding electrode 2 is inserted fixedly into a pipe 1 made of the same material with an actual machine thin pipe through a rubber plug 6. Then the electrode 2 in the pipe 1 is coated with a thin insulating tube 2a. Then the reference electrode 3 is fixed in the hole bored previously in the pipe 1. The part of this electrode 3 in the pipe 1 is covered with the thin insulating tube 3a. Then a resin 4 is filled in the pipe 1 and then the external surface of the pipe 1 is insulated by a heat-shrinkable tube 5 except constant area. This probe is used to measure the polarization resistance by an iron electrode even during the plant operation.
