Leakage Tester
In the field of leak testing, we offer three different leak testers: LEAK-01, LEAK-01H and LSST-01.
Packaging materials with weak points such as seal seams or products that are exposed to a pressure difference can be tested for their sealing qualities and durability, failure and creep limits as well as compression resistance. The devices can be used for a wide range of packaging forms.
The LEAK-01 model tests the tightness of seals of various packages by the differential pressure method in water and thus detects leakage and deformation in vacuum due to bubble leakage.
The LEAK-01H and GB M-2 do the same in air and measures the pressure rise of the vacuum due to escaping gases.
The sealing quality of stronger bags, bottles, tubes, caps and other packaging is checked by the LSST-01 device. With the overpressure method, the creep and failure limits as well as the compression resistance can be measured quantitatively. In addition, the volume flow can be precisely adjusted and recorded. Numerous accessories are available for this device, e.g. for testing bags that are open on one side.
For stronger and larger packages, we recommend our noise protection chamber.
Overview of Leakage Tester
