Vacuum Leak Tester

The Vacuum leak tester for PET bottles is designed to check the leak integrity of pet bottles to splice or pin holes. To operate the machine and to test the PET bottle sample, submerge the sample in the water within the vacuum chamber and leave the vacuum chamber to form a differential pressure between the inside and outside of the specimen. The leakage property of the specimen could be obtained by examining the steady development of bubbles from the specimen and by inspecting that how the specimen inflates and restores to its original shape after the vacuum release.
