Using the standard test hoods we show, you can check all the places that can normally be found on vessels or in a weld. Due to its extraordinary elastic packaging, it is also possible to check rectangular areas, in case of a certain deviation from perpendicularity.
It does not even prevent the checking of edge irregularity. In these cases, the test bell must be pressed further to create a vacuum.
