Abstract

PURPOSE: To measure leakage of a test container quantitativiely with high sensitivity by the following way. The space above and below the tip of a balance is divided into two, the upper room and the lower room, by the liquid in the container. the upper room is connected with a test container. Inclination of the balance, which is occured by pressure difference getween the upper and lower rooms, is detected.
