The Leeb Material Hardness Tester PCE-900 measures the hardness of nine different metals using the Leeb rebound method. This means that with the material hardness tester a firing pin bounces on a metallic surface and the intensity of the rebound is used as an indicator of the material hardness. The Material Hardness Tester PCE-900 measures the metal hardness in 6 different hardness scales.
