Lab use offline Plastic Bottle Leak Tester is composed of the mainframe and the vacuum chamber.
A test sample is placed into a vacuum chamber with water and the air above water level is evacuated by a venturi vacuum ejector. A pressure difference is created inside and outside the sample and leakage can be observed and identified when the sample is inflated and streams of bubbles appear.
Lab use offline Plastic Bottle Leak Tester uses vacuum ejector to generate stable vacuum environment.
1. The leak test requires no electricity
2. High leak test efficiency
3. Strong cast vacuum chamber
4. Different chamber sizes available
5. No calibration needed
6. No vacuum pump required
7. Easy installation, start-up and operation
8. Low maintenance
