Uses the bubble method to show leak location from a pack

A simple, visual way of seeing if, and where, a leak is occurring from a test pack. Ideal for testing packaging of food, drugs, medical instruments, car & electronic components and many other products. Complies with ASTM D3078.

There are three test chamber sizes, to suit pack size.
MFY270 – 270mm (dia) x 210mm (h)
MFY360 – 360mm (dia) x 590mm (h)
MFY460 – 460mm (dia) x 580mm (h)

The pack is immersed inside the water filled test chamber. The lid is closed and a vacuum created inside the chamber, to a user-preset level. The test vacuum is controlled by a pressure sensor and cuts off automatically when the preset vacuum is reached.

The differential pressure between the inside of the pack and surrounding water drives gas out through any leak points on the pack as bubbles.
