Rockwell hardness testers are used to determine the hardness of metals and alloys by measuring the depth of penetration under a defined force. This series includes five models: manual (LHR-150A), electric (LHR-150DT), digital (LHRS-150), and two touchscreen model (weight load version MHRS-150 and electric load version MHRS-150F). They are suitable for Rockwell hardness testing of ferrous and non-ferrous metals, hardened steel, tempered steel, annealed steel, sheet of various thicknesses, carbide materials, powder metallurgy materials, hardness and thermal spray coating.
