Main features of the instrument

1. The optical system designed by senior optical engineers not only has clear images, but also can be used as a simple microscope, with adjustable brightness, comfortable vision, and not easy to fatigue after long-term operation;

2. It has three test methods, Brinell, Rockwell and Vickers, and seven-level test force, which can meet various hardness test requirements;

3. The cast shell has a stable and non-deformed structure in one-time molding, high-grade pure white car paint, strong scratch resistance, and it is still bright as new after many years of use;

4. Our company has the ability to research, develop, design, produce and process by ourselves, and provide parts replacement and maintenance upgrade services for our machines for life;

The main purpose and scope of use of the instrument:

1. Determine the Brinell, Vickers and Rockwell hardness of ferrous metals, non-ferrous metals and cemented carbides:

2. Brinell hardness of castings, annealed steel, normalized steel, non-ferrous metals and soft alloys;

3. Rockwell hardness of heat-treated materials such as quenching and quenching and tempering;

4. Vickers hardness of nitriding layer, ceramics, thin plates, metal flakes, electroplating layers, and small parts;
