The invention relates to a testing device for ultrasonic bar ( 30 ) testing, comprising a container ( 20 ) a) with a chamber disposed therein where the ultrasonic testing is carried out which b) is provided with at least one through-passage ( 28 ) for bars which are to be tested and which c) has at least one inlet and at least one outlet for a coupling fluid ( 52 ), especially water, whereby the inlet and outlet are arranged in such a way the coupling fluid ( 52 ) is circulated around the bar ( 30 ) in a cross-wise direction in relation to the longitudinal direction thereof ( 32 ), in addition to comprising at least one ultrasonic test head ( 46 ) which is directed at the bars ( 30 ). The chamber has a non-circular cross-section perpendicular to the longitudinal direction ( 32 ) of the bars ( 30 ) and the cross-section of the chamber is adapted to the profile of the bars ( 30 ) in such a way that the width of a gap ( 42 ) running between the bars ( 30 ) and the wall ( 40 ) of the chamber is substantially maintained.
