发明名称 Method for tightness testing of closed vessels, test chamber tester and testing system therefor
摘要 In order to obtain a reliable idea of the state of tightness for tightness testing of containers filled with liquids in which a pressure differential DELTA p is created between the interior of the container and its exterior, and also relative to the container wall in contact with the filling, an impedance measurement (7) is performed using measuring electrodes (3a, 3b) on the exterior of container (1).
