Main Features
1.LED digital control, laboratory process automation
2. Set pressure and hold time
3.PVC operation panel, film button, the operation more convenient
4. High-quality thickened plexiglass sealed drum, wall thickness 15mm
5. Digital Preset Test Vacuum and Vacuum Hold Time
6. Precise pneumatic components, superior sealing performance
7. Automatic constant air pressure , without manual operation

Test principle:
Vacuuming the vacuum chamber, so that the sample immersed in water to produce internal and external pressure difference, observe the sample outside the gas outside the situation, in order to determine the sealing performance of the sample; through the vacuum chamber vacuum, so that the sample to produce internal and external pressure Poor, observed specimen expansion and release of the sample after the recovery of the shape of the sample, in order to determine the sealing performance of the sample.
