Abstract
PURPOSE: To detect securely an extremely-small pinhole, etc., with safety and by arranging electrodes on the outside and inside surfaces of a container and detecting the both conducting.
CONSTITUTION: Porcelain container 1 is taken in water tank 2 filled with water or a solution containing salts, container 1 is filled with water or a solution of salts, and bar electrode 3a and ring electrode 4a are arranged inside and outside container 1. Electrode terminals inside and outside the container are connected to voltage load instrument 7 with an incorporated current or voltage display unit. If container 1 has a pinhole, a current flows via the water or solution of salts and the propriety of container 1 can be judged by reading a change in this current.
