The PHBR series portable Briness & Rockwell hardness testers are designed and developed based on the PHR series testers according to 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. They can solve most of the hardness testing problems in the industry. HBR series Brinell & 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 international trade.
