The product is placed in a sealed chamber filled with water. Reducing the pressure outside the package creates a pressure differential between the inside and outside of the package; the seal performance of the sample is judged by observing whether a continuous stream of bubbles appears in the water.

Test procedure: check that the pneumatic lines of the seal tester are correctly connected (the connections are marked on the machine body), that the power supply is safe, and that the sealed chamber is correctly positioned. Add water and check the water level (the level should be 1-2 cm above the perforated pressure plate once the sample is in place) and make sure all test samples are ready before starting the test.
