C Clamp Brinell & Rockwell Hardness Tester

C-clamp Brinell and Rockwell hardness tester is designed and developed according to the basic principle of Brinell and Rockwell hardness testing methods. The test principle, test conditions and test accuracy are all up to the international standard ISO6508/6506.

The PHBR series hardness tester can work as both Rockwell hardness tester and Brinell hardness tester. It consists of C- shape frame, screw arbor, and test head. Rockwell hardness testers are mainly for products or semi-finished products after final heat treatment; Brinell hardness testers are mainly for raw materials, castings, forgings, or semi-finished products without heat treatment.


Advantages of C Clamp Brinell & Rockwell Hardness Tester

  • Test Function. Combined Brinell and Rockwell test functions in one instrument. They can solve most of the hardness testing problems in the industry.

  • Test Method. Test method follows Brinell and Rockwell hardness test, C Clamp Brinell & Rockwell Hardness Tester have a higher testing accuracy. The test results meet most requirements of product standard or drawings and can be well accepted in the international trade.

  • Wide Application. Different modes and anvils are available for parts in various sizes and shapes.
