Micro Vickers Series hardness testers are advanced precision testing systems suitable for hardness analysis in laboratories or production environments. Vickers hardness testers are versatile and user-friendly systems, designed for the accurate hardness testing of small precision parts, thin materials, coatings, wires and case depth determinations. Macro Vickers testers offer increased test force to go beyond the range of a micro tester to measure substances like hardened steel, martensite and more.
