Product overview
The HB-3000 is a mechanical Brinell hardness tester using a closed-loop, weight-based loading system combined with an optical measurement method for indentation diameter. It is designed for Brinell hardness testing of cast iron, steel, non-ferrous metals, soft alloys, hard plastics and bakelite. The tester features straightforward operation, manual optical measurement via microscope, and hardness evaluation by table lookup or calculation. It is intended for routine hardness control in workshops, technical schools and research laboratories.
