Automatic hardness tester for Rockwell, Brinell, Vickers and CHD test methods in compliance with ASTM and ISO hardness standards. The LD 3000 AF is built for measuring the thickness of the superficial hardness and will determine (CHD) Case Hardness Depth from 0.12 mm to 2 mm, with no need to destroy the specimen or to separate material types before performing the test. With just one measurement it reduces hardness testing time and costs compared to traditional polished cross section of Vickers and knoop methods. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). This hardness tester is entirely motorized and it is equipped with a wide touchscreen for ease in test planning and a clear view of results. Statistics and CHD charts are automatically generated and can be stored with the test session in the large archive. User friendly interface with conversion tables and round correction values for tests on covex cylindrical surfaces or various diameters. For hardness case depth test with non-destructive method on all metals: Iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing.
