Abstract
A leak testing device includes a chamber which is hermetically sealed towards the environment, having a test object filled with a test gas that is positioned in the chamber. In the chamber, a partial-pressure sensor is arranged that selectively responds to the test gas, but not to the filler gas. Thus, a leak test can be simply performed without high vacuum and without mass spectrometers.
