MODEL PHBR-4-3

PORTABLE C-SHAPE BRINELL & ROCKWELL HARDNESS TESTER

      PHBR-4-3 C-clamp type 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 ISO 6508 / 6506.

      The PHBR series hardness tester can work as both Rockwell hardness tester and Brinell hardness tester. They can solve most of the hardness testing problems in the industry. PHBR series Brinell and Rockwell hardness testers 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.

      It applies for huge or medium-size parts not available for magnetic type. 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.

Feature & Use
