Pressure decay

The method for measuring the absolute pressure drop is the one most commonly used.

The product under test is brought to test pressure and after a period of settling is checked by the pressure variation in time of the test. The test is passed if the pressure drop is less than specificated in the test parameters.
This method can also be applied with negative pressure (vacuum).

Our sales engineers are at your disposal to help you choose the instrument that best suits your testing needs.
