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 producing unleaky containers comprising:manufacturing a plurality of closed containers; 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 said closed containers; 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...
