Portable Leeb Hardness Tester Applications The Portable Leeb Hardness Tester is a versatile and accurate instrument designed for measuring the hardness of a wide range of metallic materials. It is ideal for quality control, production inspection, maintenance, manufacturing, metallurgy, automotive, aerospace, power plants, heavy engineering, and fabrication industries. The tester is particularly useful for hardness testing of large workpieces, installed machinery, moulds, pressure vessels, bearings, castings, forgings, and other components where traditional bench-top hardness testers are not practical.
