C-Shape Rockwell Hardness Tester PHR Series
Structure And Application
- It is a 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.
Features
- Follow Rockwell hardness test method and test condition, and the result is reliable.
- Fix the instrument to part and clamp it and test the hardness of part, no need to move the part.
- Test fast, convenient, non-destructive.
- Structure as simple as micrometer, accurate, convenient, repeatable.
- As accurate as desk tester, error less than 1.5HRC.
Application Instruction
- Compared with small type, C-shape type applies part clamping structure and similar reading system as micrometer, so it is prior to small type for its good stability, repeatability, accuracy.
