Leak testers
With compressed air or hydrogen
Ceta Testsysteme will be exhibiting its devices for leak and flow tests at Motek. Compressed air and hydrogen are used as test media for the leak tests.

Compressed air can be used to test leak tightness against liquids, as the viscosity of air is lower than that of liquid media. The company often uses the differential pressure test method, in which the leakage-related pressure drop is measured as a pressure difference against a sealed reference volume. The minimum leak rates that can be detected using this method are in the order of 10 to3 mbar*l/s. If the leak consisted of only a single hole, this would have a diameter of around 20 µm at a test pressure of 1 bar.
