LD 250
Universal hardness tester for Vickers, Rockwell, Superficial Rockwell and Brinell hardness test methods in compliance with ASTM and ISO hardness standards. LD 250 is a top level bench hardness tester for fully automatic test cycles including indentation autoreading through the high resolution camera. It is entirely motorized and equipped with an automatic turret with indenters and magnification lenses. LD250 allows hardness testing in different hardness scales with just one testers, without the need of several testers in own laboratory. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). Wide touchscreen for easy test planning and a clear view of results. Statistics and charts are automatically generated and can be stored with test sessions in the large archive. User friendly interface with conversion tables and round correction values for tests on covex cylindrical surfaces or various diameters. Hardness tests on all metals: iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing. Knoop test on ceramic and glass materials.Test loads: Depending on the models - From 1 to 3000 kgf (From 9,807 to 29421 N)
