HARDNESS TESTER

HARDNESS TESTER

Brinell, Rockwell, Vickers hardness tester

Electric universal hardness tester have stable and reliable performance, can meet Rockwell, small load Brinell and Vickers hardness test requirement, its convenient for the user to do hardness testing of a variety of materials at the same time, can avoid the artificial error of measurement effectively, its a economical and practical multi-function equipment.

 

Main function and features:

1.Leading variable load structure design, can easily switch test force, high test precision, good repeatability.

2.The dial reads the Rockwell hardness value directly, indicator responses sensitively, show the hardness value accurately, which is more than national standard; It indicates the Brinell and Vickers hardness value by measuring microscope.

3. To compare with Optical type, this machine optimizes the inner physical mechanic structure, high accuracy, stable function, it is convenient to maintain.

4. The shell is one step casting molding with special foundry process, stable structure and no deformation, can work under relatively harsh environment; Pure white car painting and its class is high, have scratch resistance ability, its still brightness used for years.

5. We have our own research and development design, production and processing ability, our machines provide life-long time parts replacement and maintenance upgrade services.

 

Main Uses:

1. Chilled steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.

2. Cast iron, nonferrous metal, especially for soft metal, such as pure aluminum, lead, tin, etc.

3. Carburizing, nitriding and decarburization layer, the surface hardening layer, electric plating and coating.
