1. Introduction and application
The instrument has a variety of test force and a variety of pressure head for the determination of metal materials or samples of the Brinell, Rockwell, Vickers
Hardness. For ferrous metals (steel, cast iron, soft steel, hardened steel, etc.) and non-ferrous metals (aluminum, Copper alloy, etc.) hardness, and determination of carbide, carburized layer hardness and chemical processing layer.
HBRV (D)-187.5D1 type Brinell hardness test uses a rotating force of transformation institutions and optical measurement systems
System, the body measuring device is equipped with microscopes. Easy to use, reliable, variable charge, showing the value of the stable, widely used in engineering, factory workshops, laboratories, universities and research institutions
