The LEAK-MASTER® EASY is designed for testing almost any stable and flexible food packaging, including vacuum packaging. The test packaging is placed in the water-filled chamber and the air space above the water level is evacuated using the Venturi nozzle. As the immersed packaging inflates (due to the resultant vacuum), air or filling gas escapes at leaking points, bubbling up in a clearly visible manner. This tester can quickly and easily determine whether and at what point the packaging is leaking, all in less than 30 seconds. Installation and operation are uncomplicated, and operating costs are low because only water and air are used instead of expensive test gases.
