Vacuum sealing tester

Test Principle
1, By vacuuming the vacuum chamber, the sample immersed in water is subjected to internal and external pressure difference, and the gas escape in the sample is observed to determine the sealing performance of the sample.
2, By vacuuming the vacuum chamber, the sample is subjected to internal and external pressure difference, and the shape of the sample is recovered after the sample is expanded and the vacuum is released, thereby determining the sealing performance of the sample.
3, The instrument meets many national standards: GB/T 15171, ASTM D3078.

Features
1, Manual control is adopted to keep pressure. It is easy to operate and has stable performance.
2, Pneumatic components are manufactured by manufacturers and have stable performance. Pressure holding instability due to pneumatic components.
3, Glass (acrylic) sealed barrel, wall thickness increased to 15mm, compressive strength of sealed barrel
4, Electronic pressure holding device to reduce mechanical wear and make pressure retention time.
5, PVC operation panel, pressure pointer display, convenient for users to quickly view pressure values

Application
The sealing tester is suitable for sealing test of packaging bags, bottles, tubes, cans, boxes, etc in food , dairy chemical, automotive, electronic components, stationery and other industries. It can also be used to test the sealing performance of the specimens after drop the withstand pressure test.
