PHR Rockwell Hardness Tester

 

PHR Rockwell Hardness Tester is a great innovation in Rockwell hardness testers. Miniaturization and portability are realized without reducing testing accuracy. The smallest model weighs only 0.7kg, and the operation is similar to that of a micrometer.

 

The tester is suitable for testing a wide range of metals from soft metals to very hard alloys, including aluminum alloys, copper, copper alloys, mild steel, stainless steel, quenched steel, tempered steel, carburized steel, and carbide. With a variety of anvils, the tester can be used to test sheets, cylinders and many other shapes. It can also test the hardness of pipes from both inside and outside.

 

Tianxing Rockwell testers read directly in fifteen Rockwell scales: A, B, C, D, E, F, G, H, K, L, M, P, R, S, and V. The accuracy meets the requirement of GB/T230, ISO6508 and ASTM E18. The test is accurate, relatively fast and simple, with small indentation. Thus, it is suitable for one-by-one inspection of batches of finished or semi-finished workpieces. The readings can be converted into HV, HB or tensile strength through conversion tables.
