The effectiveness of offline leak detection is highly dependent on an operator continuously sampling packages during a production run and maintaining this discipline throughout the production run.
The random sampling machine eliminates this requirement by continuously sampling the product automatically and eliminating the subjective nature of a person loading the machine.
A person will not test a package that has a clear leak, as they know it will fail, thus distorting the actual profile of a production run, while a machine will collect the sample and report the result objectively.

As the sampling regime is more comprehensive than offline testing, any change in the appearance of leaking packages could be used to trigger alarms.
Small groups of leaking packages can go unnoticed again.Due to the increased number of packages tested, leak information is stored in place of each test.
In-Line Leak Detection – In-line or 100% leak detection has a number of key advantages, as it involves testing each individual package that comes out of the sealing machine.
Not only are all leaking packages removed from the production line, but the information collected is also a 100% picture of the process and every change in the process.
As a machine is testing each package individually, the machine can instantly recognize any change in the leak rate of the process.
The occurrence of leaks and any changes will trigger a set of alarms, from an initial alarm to say that the leak rate has increased to a final alarm that will stop a sealing machine in the event of a major increase in the occurrence of leaks.
