Get a real reference of your new and used test pieces. In our laboratory, we produce high-quality reference photos that enable you to easily and reliably compare the display of your control body, even under UV-A radiation. You determine which test specimen (MTU, PSM-5, ASME test block, ISO 3452-2, etc.) is displayed with which test equipment and which test procedure. We are also happy to carry out referencing using test equipment and systems from other manufacturers.
