negative pressure leak test equipment/Air Leakage tester/Packaging Leak Testing Machine

Application: it is suitable for the sealing test of packaging bags, bottles, tubes, cans and boxes in food, pharmaceutical, medical equipment, daily chemical, automobile, electronic components, stationery and other industries.It can also be used to test the sealing performance of the specimens after dropping and pressure test.

Testing principle:

By vacuumizing the vacuum chamber, the pressure difference between the inside and outside of the sample immersed in water is generated, and the gas escape in the sample is observed, so as to determine the sealing performance of the sample.By vacuum-pumping the vacuum chamber, the internal and external pressure difference of the sample is generated, the expansion of the sample and the shape recovery of the sample after the release of vacuum are observed, so as to determine the sealing performance of the sample.
