PHR-8-4 C Clamp Rockwell Hardness Tester


PHR-8-4  C clamp Rockwell hardness tester is designed according to the basic principle of Rockwell hardness test. The principle and structure of this kind of hardness tester is in accordance with the American Standard ASTM E110.

Compared with small type, C clamp Rockwell hardness tester applies part clamping structure and similar reading system as micrometer, so it is prior to small type for its good stability, repeatability, accuracy.

This portable Rockwell unit 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.
