Off-line Leak Detector for testing Trays & Cases of Packed Product

Final non-destructive inspection, for pack integrity checks on product already packed inside their transit cases or trays.

The Dansensor® LeakPointer II E2 employs a very sensitive test method capable of detecting microleaks. The problem is caused by poor seals, product entrapment, seal contamination, or pinholes in the packaging film.

This is a non-destructive test, that minimises the product and the packaging waste caused from using destructive methods. By incorporating a large test chamber, the LeakPointer II E2 is also capable of checking a high volume of product.

In common with Dansensor’s other leak detection units, the LeakPointer 3 and LeakPointer 3+, the test method uses CO2 as a trace gas. The packs being tested must therefore contain a minimum 20% CO2.

This is a dry, non-destructive and well proven method that eliminates the more basic use of a water bath and the associated biological hazards that presents within production areas.

The Dansensor® LeakPointer II E2 is a robust, free standing unit, designed for locating at the end of the production line. Testing packages shortly after they have been produced gives a continual flow of real time information to assist in the optimisation of the packaging process and facilitate it’s continued improvement.

Complete trays, or cases, of finished product undergo a final check before proceeding to dispatch. This efficient leak check adds confidence that everything has been done, to ensure the integrity of the pack seals.

Process The case or tray(s) of product is placed in the test chamber and the lid closed. This automatically activates the vacuum pump to evaluate the test chamber amd creates a difference in pressure between the inside of the packs and the test chamber.

This pressure difference forces gas out of the pack(s) and into the chamber. A sensitive CO2 sensor detects any increase in CO2 levels within the chamber and registers a leak both visually & audibly. The finished packages must contain at least 20% CO2.

Non-leakers continue to be palletised and leakers can be investigated. Test results are stored for subsequent export / download.
