PHBR series Chain Clamp Brinell & Rockwell Hardness Tester are designed and developed based on the PHR series Rockwell Hardness testers and follows the test method of the Brinell and Rockwell hardness test and function as both Brinell & Rockwell hardness tester. which can tests accurately the castings, forgings, steels and nonferrous metal and work pieces made of all kinds of metal materials under kinds of heat treatment on-site. The test principle and accuracy comply to standard ISO6506, 6508 and ASTM E110. So it is usually Used for manufacturing inspection and acceptance inspection to replace Leeb hardness tester with lower accuracy.
