Product Description
Negative pressure 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.
Negative pressure leak tester uses vacuum ejector to generate stable vacuum environment.
