Rockwell hardness of the surface is also very suitable for testing the hardness of the work piece surface hardening, surface Rockwell hardness scale; there are three to choose from. You can test the effective hardening depth of more than 0.1mm of various surface hardening artifacts. Although the surface hardness of Rockwell Vickers hardness tester accuracy is not high, but as a heat treatment factory quality control and qualified inspection testing methods, has been able to meet the requirements. Moreover, it is simple, easy to use, low price, rapid measurement; hardness value can be read directly, etc., the use of surface Rockwell hardness tester can heat the surface of the bulk of the work piece by piece for rapid non-destructive testing. This is for the metal processing and machinery manufacturing plant of great significance. When the surface of the hardened layer of thick, they can be used Rockwell hardness tester. When the hardened layer thickness of 0.4 ~ 0.8mm, can be used HRA scale. When the hardened layer thickness of more than 0.8mm, can be used HRC scale.

PHR Series Portable Rockwell hardness tester surface is very suitable for testing the hardness of the work piece surface heat treatment, to test the effective depth of more than 0.1mm of the surface heat treatment of a variety of work pieces. Simple, easy to use, low price, the hardness value can be read directly.
