The Mitutoyo Hardmatic HH-V400 is a state-of-the-art, rebound-type portable hardness tester designed for fast, accurate, and versatile hardness measurement of metallic materials. Engineered for field use, it combines rugged portability with advanced functionality, making it ideal for quality control, maintenance, and inspection tasks across various industries.
Using the Leeb hardness testing principle, the HH-V400 operates by launching a steel ball via a spring-loaded impact hammer onto the surface of the test material. The device then measures the rebound velocity to calculate a Leeb hardness value (HL), which can be automatically converted into multiple standardized hardness scales including Vickers (HV), Brinell (HB), Rockwell (HRC/HRB), Shore (HS), VHS, and tensile strength (MPa).
Its redesigned LCD interface, intuitive menu system, and rechargeable battery (up to 8 hours of continuous use) make it exceptionally user-friendly. The HH-V400 also supports extensive data management, allowing users to store thousands of test results, organize sample groups, and perform statistical analysis directly on the device.
