C Shape Portable Rockwell Hardness Tester PHR series

PHR series C-Shape Rockwell hardness testers are designed according to the basic principle of Rockwell hardness test. The principle and structure of hardness tester is in accordance with the American Standard ASTM E110.

Compared with small type, C-Shape type applies part clamping structure and similar reading system as micrometer.

It is small, light, accurate portable hardness tester. It consists of C- shape frame, screw arbor, and test head. It could test flat or curve parts as long as the parts could be clamped and the test surface erects the test head. It could be applied in production inspection and acceptance inspection to replace low accurate Leeb hardness tester.

►  Test Principal: Follow Rockwell hardness test method and test condition and the result is reliable.

►  Simple Operation: Fix the instrument to specimen, clamp it and test the hardness of specimen. No need to move the part

►  High Reliability: Structure as simple as micrometer, accurate, convenient, repeatable.

►  Highly Accurate: Test fast, convenient, and non-destructive.  As accurate as benchtop tester, error less than 1.5HRC.
