Hardness Tester Accessories

Leeb Hardness Test Blocks : We offer wide range of Test Block for Digital Portable Hardness Tester of all range and scale. We offer low, medium and high hardness test block with all scale Rockwell, Brinell and Vickers hardness tester.

Using the Genuine Leeb Scales (HL) : The Leeb rebound method was invented in 1975. Since then, Proceq has maintained the genuine Leeb standard HL. That means, a measurement of a sample showing a result of 750 HLD by Proceq in 1975, done with the first generation Equotip, would still deliver the exact same result today, done with the most recent generation. With Equotip test blocks, end users can check if their testers conform with this hardness unit, similarly to using a ruler for length measurements. During a Leeb hardness measurement, an impact body with a hard ball indenter is launched by spring energy against the sample, and then rebounds. The ratio of the rebound velocity vr to the impact velocity vi multiplied by 1000 yields the hardness value HL (Leeb hardness).
