Leak test aims to examine the sealing quality and integrity of a package, especially when the package is exposed to a pressure differential. The analysis for package leakage is meaningful for prolonging product shelf life.
MFY-01 Hermeticity Tester Hermetic Seal Test is designed for gross leak test of packages for food, drugs, medical instruments, daily chemical products, cars, electronic components, stationeries and other industrial products.
Firstly submerge the specimen in the water within the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The leakage property could be obtained by observing the steady progression of bubbles from the specimen and how the specimen expands and restores to its original shape after vacuum release.
