Product Overview
The AULIMET MR-HD700 Portable Hardness Tester is a versatile universal hardness testing solution engineered for fast, accurate, and reliable metal hardness measurement. By integrating both Leeb impact and UCI (Ultrasonic Contact Impedance) testing technologies, it provides precise hardness readings across a wide range of materials, including steel, aluminum, cast metals, and various industrial alloys. The device supports multiple hardness scales, such as Brinell (HB), Rockwell (HRC/HRB), and Vickers (HV), making it suitable for diverse testing requirements. Designed for manufacturing, metal fabrication, inspection, and quality control applications, the MR-HD700 delivers dependable performance in both workshop and field environments. Its portable design, advanced measurement capabilities, and multi-scale compatibility make it an ideal choice for professionals seeking accurate and efficient hardness testing.
