Digital Vacuum Seal Strength Tester Packaging Air Leak Detector ASTM D3078
ASTM D3078 Digital Vacuum Sealing Performance Tester Packaging Air Leak Detector
1. Application
It is suitable for the sealing test of packaging bags, bottles, tubes, cans and boxes in food, pharmaceutical, medical apparatus and instruments, daily chemical, automobile, electronic components, stationery and other industries.It can also be used to test the sealing performance of the specimen after the drop and pressure test
2. Test principle
By vacuuming the vacuum chamber, the pressure difference between inside and outside of the sample immersed in water is generated, and the gas escape inside the sample is observed, so as to determine the sealing performance of the sample;By vacuuming the vacuum chamber, the pressure difference between inside and outside of the sample is generated, and the shape recovery of the sample after expansion and vacuum release is observed, so as to determine the sealing performance of the sample.
