Witt-Gasetechnik Leak-Master leak test devices

The Leak-Master series of leak test devices locate small holes in rigid or flexible packaging quickly and precisely, enabling inert gas and vacuum packaging to be tested for leaks via a method that doesn’t involve trace gas. The Leak-Master Easy is the entry-level model in the series.

The test product is placed in a chamber filled with water. When the lid is closed, the air space above the water level is evacuated, the package inflating underwater. If air bubbles emerge, there is a leak. The test method is straightforward and has the additional advantage that the weak point of the packaging is visible.

The Leak-Master Easy Plus records, saves and communicates (via ethernet and SD card) its test program and results. This means QC/QA managers can check all leak test results at any time.

Operation is via a coloured touch screen, enabling products, users and test programs to be configured rapidly and easily. After logging on to the device and selecting the product to be tested, the user places the packaging in the test chamber, closes the cover and starts the program.

The preset vacuum is automatically generated and maintained over the defined time period. The user performs a visual inspection and enters whether the packaging was leak-proof or not after the test process. The end result is a standardised test sequence that can be reproduced at any time.

Special test programs are also possible, eg, height simulation. At the touch of a finger, the system can simulate a flight profile. Variants with CO2 as the test gas are also available. The test is performed without contact in a vacuum chamber using a sensor, which logs any escaping CO2.

The inline variant Leak-Master MapMax can be integrated seamlessly into a packaging line. Testing for carbon dioxide is also carried out here, but fully automatically and with a speed of 15 cycles/min so the entire production is logged. All detectors are available in multiple chamber sizes.
