For tightness testers with a plurality of in-line test stations (1) on a conveyor it is proposed to supply the tightness-relevant measurement signals from the chambers by detecting pressure change measurements via pressure sensors or electrical impedance measurements via electrodes that occur at the test stations over a time interval. The signals are supplied through multiplexers (5) to a central evaluation (9).

1. A method for in-line leak testing containers comprising:providing a number of leak test stations, each for at least one container, on a movable conveyor wherein the test stations move with the conveyor; loading said stations with containers to be tested; generating an electric signal output on the movable conveyor at each of said stations in dependency of leakage of said container under test in a station considered; and applying the electric output signals of said stations subsequently, one after the other to an input of a common evaluation unit on said movable conveyor and generating by said common evaluation unit leak indicative signals for each of said containers under test.
