Bench hardness tester
AT250
Enhanced version of the AT130 model with advanced electronics and the most up-to-date communication systems.
A real innovation in the Rockwell tester testing field, with thousands of units sold throughout the world from the early 70’s, due to its fast test cycle and the ability to test bulky items with the unique clamping system for overhanging pieces and the absolute insensibility to bending and deflection.
