HBS3000-212
Digital Brinell Hardness Tester
The HBS3000-212 is a digital Brinell hardness tester. Its key features include high-precision test-force control enabled by a closed-loop control system and a wide range of selectable test forces, allowing it to accommodate a broad spectrum of testing applications—from soft metals to hard alloys. Indentation measurement, however, still requires manual operation with a micrometer eyepiece. The instrument employs a precision stepper-motor-based closed-loop control system combined with optical measurement technology, making it primarily suited for hardness testing of cast iron, steel, nonferrous metals, and nonmetallic materials. Integrating optical, mechanical, and electrical technologies, it is widely applicable in factory workshops, laboratories, and research institutions.
