How it works
Most products are affected by pressure changes when transported by air or driven through high-altitude regions. Seal-Check reveals weak packaging areas — the sea-level simulation can run in either a dry chamber or a water-filled chamber.
-
Submerge the sample
Samples such as food packaging are placed in a test chamber filled with water. Closing the chamber presses the package below the water surface.
-
Create a vacuum
The air above the water is then evacuated to create a vacuum — simulating the lower pressure a package meets during high-altitude transport.
-
Spot the leaks
Any air or gas trapped in the package escapes through leak points, such as faulty seals, as a clear, easy-to-pinpoint stream of bubbles.
