The testing machines we develop are used for pressure, mechanical stress and external testing. Our pressure test systems work on the basis of comparing air pressure differences over time. High-pressure complete test systems operate with liquid media (usually water) at up to 2,400 bars. They are intended for pressure resistance testing using both cycling and dynamic burst tests. The course of testing is always recorded and the record is archived in a database. In addition, all data are displayed online in graphical form during a test. Another category consists of mechanical testing machines that are used to verify the robustness of switches, bends, materials, etc.
