Abstract:
The invention relates to a testing device for testing the tightness of containers (2), comprising a supply unit (3) for supplying the containers (2), a testing unit (4) for testing the tightness of the containers (2), a diverting unit (5) for diverting tested tight containers (2), and a discharge unit (6) for discharging containers (2′) tested to be untight in the testing unit (2). The testing unit (4) has at least one individual testing chamber (42) for testing individual containers and at least one multiple testing chamber (41) for receiving a plurality of containers in order to simultaneously test multiple containers (2). The testing device also comprises a control unit (10) which is designed to supply possibly untight containers (2′) which have been discharged by means of the discharge unit (6) from a multiple testing chamber (41) individually back into an individual testing chamber (42) in order to carry out an individual test of said containers.
