The HBRV-187.5 Electric Brinell-Rockwell-Vickers hardness tester has three test methods of Brinell, Rockwell and Vickers, and is a multi-purpose and multi-functional hardness tester with seven test forces, which can meet various hardness testing requirements of users. The application, holding and unloading of the test force are completed automatically. It has a wide range of use and is easy to operate. It is a standing hardness testing machine for industrial and mining enterprises and scientific research institutions.
Application:
Quenched steel, surface quenched steel, hard alloy steel, cast iron, non-ferrous metals, various quenched and tempered and annealed steels, hardened steel sheets, also suitable for softened metals, surface heat treatment and chemical heat treatment, etc.
