This system uses a transparent acrylic case to allow viewing of the packages while they are subjected to an underwater vacuum test. Even small leaks can be observed, and adjustments can be made to sealing equipment once the location of the leaks are found. A stainless steel cage ensures the pack is completely submerged under water during the test.
The system uses a compressed air driven vacuum generator to provide a constant vacuum within the chamber. An electronic vacuum gauge reads the pressure within the case and allows the user to make adjustments to the pressure regulator. This also allows for repeatable testing procedures as the same pressure can be used to compare results.
This system provides a simple and inexpensive method of locating the smallest of leaks with minimal fuss. The test procedure is fast and easy to use, yet reliable and highly sensitive.
