Package leak tester MFY-05S is suitable for leakage test for bags, bottles, barrels ,Cleaning Wipeand other products. Negative pressure test mode can effectively compare sealing performance. It is ideal testing equipment for food, plastic flexible packaging, wet wipes, pharmaceutical and other industries.
 

Test principle

Leak tester using the negative pressure method principle, vacuum the vacuum chamber to make the immersed water sample have internal and external pressure difference. Observe gas escape situation to determine the sealing performance of the sample. Or vacuum the vacuum chamber to make the immersed water sample have internal and external pressure difference. Observation sample expansion and shape of the samples after the release of vacuum recovery and liquid infiltration condition to determine the sealing performance of the sample.
