WITT LEAK-MASTER PRO 2 leak tester for modified atmosphere packaging

The WITT LEAK-MASTER PRO 2 tests the leak-tightness of modified atmosphere packaging. It is now available with two larger chambers, allowing food producers to have four chamber sizes to test packages of almost any size.

The device tests packages for escaping CO₂, which features in many modified atmosphere packages. To do this, a vacuum is generated in the test chamber. If there is a leak, the protective gas escapes from the test product, which is detected by CO₂ sensors. The packaging remains intact during the test.

The test takes only a few seconds. Depending on the packaging and the test conditions, leaks down to 10 micrometres can be detected. The test is carried out automatically with a preset vacuum and over a defined period of time. LED illumination of the chamber provides a clearly visible signal of the test result: if the packaging is leak-proof, the chamber lights up green; if the packaging is not leak-proof, the chamber lights up red.

The PRO 2 has a compact design and requires little space. In the standard version, the unit is operated with compressed air. An optional version with an electric vacuum pump is available, for all chamber sizes.

All measurement results including date, time, product details and name of the tester are stored and can be exported for archiving. It is also possible to analyse the data using MS-Excel, for example. It manages up to 1200 products as well as names, passwords and barcodes of up to 60 users.
