LEAK TESTING IN A WATER BATH
Bubble leak testing in a water bath is a visual test method e.g. for leak testing of packaging. The test item is completely immersed in water. If there are leaks, visible air bubbles rise.
LEAK TESTING WITH TRACE GAS
The leak testing with trace gas is done using gas sensors. The test item (packaging) must contain the defined trace gas. If the test item is leaky, the escaping gas is detected by the sensors.
