PHB-1 Pin Impact Brinell Hardness Tester

PHB-1 Pin Impact Brinell Hardness Tester
The PHB-1 Pin Impact hardness tester is designed following the Brinell hardness test method. The test force is controlled by a shear pin. After reading the diameter of the indention with the reading microscope, the Brinell hardness value can be obtained from the look up table.

This kind of hammer impact Brinell hardness tester is capable of testing from small to very large specimens. It is especially suitable for assemblies inconvenient to be taken to the lab and not allowed to be cut. The test can be completed in any direction to test the hardness of upper, lower and lateral part of the specimen.


The PHB-1 Pin Impact hardness tester can be widely used to test the hardness of forgings, castings, steels, nonferrous metal and its alloy products, and to test the hardness of annealed, normalizing and tempered mechanical parts.

Compared to the rebound type hardness tester, the Brinell hammer hit tester 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.
