Affri LD Universal Hardness Tester
Universal hardness testers for Vickers, Rockwell, Superficial Rockwell and Brinell hardness test methods in compliance with ASTM and ISO hardness standards.
Universal hardness testers for Vickers, Rockwell, Superficial Rockwell and Brinell hardness test methods in compliance with ASTM and ISO hardness standards.
Universal hardness testers for Vickers, Rockwell, Superficial Rockwell and Brinell hardness test methods in compliance with ASTM and ISO hardness standards.
The LD 250 & 750 - The hardness tester’s head moves down until contact is made, clamps the piece, applies the force and make the indentation. The software will move to the camera view mode where the indent is automatically measured.
Automatic movements with automatic stop when contact is made. Up to 300 mm of motorized vertical stroke. The approach of the head to the peace and not the opposite allows more accurate, scable and safe measurements.
Test loads: LD250 from 1 to 250 kgf (From 9,807 to 2452 N). LD750 from 3 to 3000 kgf (From 29.4 to 29421 N)

Universal hardness testers for Vickers, Rockwell, Superficial Rockwell and Brinell hardness test methods in compliance with ASTM and ISO hardness standards. LD 250 and LD750 are top level bench hardness testers for fully automatic test cycles including indentation auto reading through the high resolution camera. Entirely motorized and equipped with an automatic turret with indenters and magnification lenses. The instrument allows for hardness measuring in different hardness scales with just one tester, 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 convex cylindrical surfaces or various diameters. Hardness tests on all metals: iron, steel, tempered steel, cast iron, brass, aluminium, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing. Knoop test on ceramic and glass materials.
