Quality control of packaging without using trace gas

Leak testing made easy

When it comes to testing packaging for leaks, WITT provides a reasonably priced solution that works without trace gas. WITT’s new “Leak-Master® Easy” uses only water and compressed air to operate the uncomplicated test system.

The “Leak-Master® Easy” is suitable for testing almost all stable and flexible food, pharmaceutical, industrial and consumer packaging, including vacuum packaging. The test system enables even the smallest leaks to be detected without any test gas. Nor is there any need for electricity. A Venturi nozzle that only requires compressed air is used instead of a vacuum pump.

The test packaging is placed in the water-filled chamber for the leak test and the air space above the water level is evacuated using the Venturi nozzle. The immersed packaging inflates due to the resultant vacuum. Air or filling gas escapes at leaking points, bubbling up in a clearly visible manner. The quality tester can quickly and easily determine whether and at what point the packaging is leaking. The test time is less than 30 seconds.

In contrast to automatic test devices with electronic detector technology and signal processing, the optical sensor of the “Leak-Master® Easy” is the human eye – always providing unambiguous results.

The solid technology also comes with a wide range of other advantages: The operating costs of this test equipment are low because only water and air are used instead of expensive test gases such as helium. The installation and operation is uncomplicated. The “Leak-Master® Easy” requires no calibration and little maintenance. What’s more, the simple, intuitive operation eliminates the need for highly trained experts. The sturdy acrylic housing is hygienic and easy to empty and care for.

Simple strength tests on the packaging can also be carried out in the dry chamber. With an optional extension set, the “Leak-Master® Easy” is also suitable for testing vacuum-packed products or products with very low gas space.

Packaging that is transported by air cargo is subject to particular stress due to different air pressures. An air pressure that typically occurs at an altitude of 9,000 feet can cause stretching of the packaging during transport at high altitudes. A height simulation test enables the “Leak-Master® Easy” to reveal potential weak points in the packaging before transport, thereby preventing damage.

The “Leak-Master® Easy” is available in five versions with chamber sizes from five to 55 gallons.
