Reasonable Price Vacuum Air Leak Tester For Packaging
Materials
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 great pressure difference is created inside and
outside the sample and any slight leakage can be observed and
identified when the sample is inflated.
