The PHBR Portable Brinell & Rockwell Hardness Tester is developed based on the PHR Rockwell Hardness Tester. Following Brinell and Rockwell test methods, the accuracy of this tester meets the requirement of ISO6506, ISO6508, ASTM E10 and ASTM E18. The direct test result meets the requirement of the drawing or specification of most workpieces. The PHBR Rockwell & Brinell Hardness Tester has 8 models in 3 series: Regular, Large and Chain Clamp. It has the construction and shape as the PHR Testers. With all the features and functions of the PHR Tester, the PHBR Tester can also be used as a Brinell hardness tester. It is suitable for testing a wide range of metals from aluminum to carbide, from castings to machined parts, and from annealed to quenched.
