The test force is controlled by a shear pin, thus resulting in accurate test force, in accordance with the test method, and error <1%.
With test force F=1580kg, indenter diameter D=7.26mm, F/D2=30. The test condition of the PHB tester is equivalent to that of the standard Brinell hardness test with 3000kgf and 10mm ball indenter.
High precision, repeatability and reproducibility, error <2-3%
With three applications as bench, C Clamp and hammer impact hardness testers, it can test the workpieces of all sizes and shapes.
Operating easily and conveniently, testing fast.
Testing cost is low with only one cheap shear pin used in each test.
It is used to test the hardness of castings, forgings, steels, nonferrous metal and its alloys, and to test the hardness of annealed, normalizing and tempered metal materials.
Compared with the common-used rebound hardness tester, it has many advantages such as higher precision, fewer factors affecting accuracy and lower requirement on the surface roughness. The test result meets the requirements of most drawings without conversion and is more widely accepted in the international business.
