Abstract

PURPOSE: To detect lining defects by inserting an electrode of one side into a conductive liquid accomodated in a conductive container having lining and by detecting a decrease of an electric resistance value between another side electrode connected to the container wall.
CONSTITUTION: In the case of a conductive container 1 having inside insulating lining, a tank for example, containing conductive liquid (for example plating liquid) 3, an electrode 4A is inserted in the liquid 3, an electrode 4B is fixed to the wall of the container 1, the electric resistance between both electrodes 4A, 4B is measured with a resistance measuring instrument 4. Namely when the lining 2 is normal, said resisting value shows infinity, while in case of caused damage the resisting value decreases extremely so that an occurred defect is detected. Further for locating a position of the defect it suffies to continue a resistance value measurement low ering a liquid level by turns.
