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 ISO 6506, ISO6508.

      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.

Feature & Use

• Brinell and Rockwell combination: Add the functions of Brinell hardness test on the basis of PHR series testers. Combined Brinell and Rockwell test functions in one instrument.
• Test principle: Test method follows Brinell and Rockwell hardness test and accuracy in accordance with ISO 6506, 6508 and ASTM E10, E18.
• Wide Application: Different modes and anvils are available for parts in various sizes and shapes.
• Traceable standard hardness blocks. Indenter is inspected with standard Rockwell hardness tester.
