Zusammenfassung:A method of and a system for checking sealed containers for pinholes with contents enclosed therein by placing a sealed container between first and second electrodes, impressing voltage across the first electrode and second electrodes to generate two discharge current flows on the container and between the first electrode and second electrode respectively, detecting the discharge currents individually and converting the difference between the detected values to a detection signal value.
