Detecting leaks by the bubble method & shows their location on the pack

A simple, visual method for seeing if and where a leak is occurring on a test pack. Ideal for testing packs in which the headspace does not contain a trace gas, such as CO2. 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)

Process  The test 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 vacuum creates a differential pressure between the inside of the pack and surrounding water. This drives gas out of any leak present in the pack and bubbles can be seen emerging.
