ASTM D3078 Digital Display Vacuum Sealing Performance Tester

ASTM D3078 Digital Display Vacuum Sealing Performance Tester

1. Product use
 Suitable for food, pharmaceutical, medical equipment, daily chemical, automobile, electronic components, stationery and other industries of packaging bags, bottles, tubes, cans, boxes and other sealing test.It can also test the sealing performance of the specimen after the drop and pressure test

2. Test principle
By vacuuming the vacuum chamber, so that the sample immersed in water produced internal and external pressure difference, observation of the sample gas escape, in order to determine the sealing performance of the sample;By vacuuming the vacuum chamber, the pressure difference between inside and outside of the sample was generated, and the shape recovery of the sample was observed after the expansion of the sample and the release of the vacuum, so as to determine the sealing performance of the sample.
