Test Principle
The seal tester adopts the principle of negative pressure test.
1. Vacuum the vacuum chamber to make the sample immersed in water produce internal and external pressure difference, observe the gas leakage in the sample, and determine the sealing performance of the sample
2. By vacuuming the vacuum chamber, the pressure difference inside and outside of the sample was generated, and the shape recovery of the sample after expansion and release of the vacuum was observed to determine the sealing performance of the sample.
