Introduction
The HBRVS-187.5 digital display Burawoy Hardness Tester is a multi-purpose multi-functional hardness machine with three test methods: Brinell, Rockwell and Vickers, and seven levels of test force. It can meet the user's various hardness testing requirements. The application, holding and unloading of test force are completed automatically. It has a wide range of uses and is easy to operate. It is a hardness testing machine commonly used by industrial and mining enterprises and scientific research institutions.
The main function
Equipped with three test methods: Brinell, Rockwell and Vickers
A multi-purpose multi-functional hardness machine with seven levels of testing force, which can meet the user's various hardness testing requirements.
Rockwell hardness, Brinell and Vickers readings all have digital LCD display
The application, holding and unloading of test force are automatically completed
Wide range of use and easy operation
Application scope
Determine the Brinell, Vickers and Rockwell hardness of ferrous metals, non-ferrous metal carbide and non-metals. It has a wide range of applications and can be widely used for determination:
a. Brinell hardness of castings, annealed steel, normalized steel, non-ferrous metals and soft alloys;
b. Rockwell hardness of heat-treated materials such as quenching and tempering;
c. Vickers hardness of nitrided layer, ceramics, thin plates, metal sheets, electroplated layers, and tiny parts.
