Description
Application
It is suitable for determining the Rockwell hardness of ferrous metals, non-ferrous metals and non-metallic materials. It is widely used in quenched steel, quenched and tempered steel, annealed steel, chilled castings, malleable castings, hard alloy steel, aluminum alloy, copper, bearing steel
Description
HRS-150 high-precision digital display Rockwell hardness tester has a novel large-screen display, menu structure, hardness value automatic calculation and display, and automatic conversion of various hardness values. The shell adopts the perfect casting process and special hole surface processing, which strictly guarantees the concentricity of the main hole of the machine. The one-cut plane processing technology ensures the flatness of each plane. The screw rod also uses a fine grinding process to ensure that the machine rises and falls smoothly and without eccentricity. Therefore, this machine ensures higher precision and more stability for the whole machine for special processing.
