The SPR-963 Leeb Hardness Tester is a portable, high-precision device designed for non-destructive hardness testing of metallic materials. Utilizing the dynamic Leeb rebound principle, it measures hardness across multiple scales (HRC, HRB, HB, HV, HS, HL) and is ideal for applications in manufacturing, quality control, and field inspections. Its compact design allows for testing in confined spaces and at any angle.
