Product Description PHR-4-3,PHR-8-4,PHR-8-10,PHR-20-12 C-Shape Rockwell hardness testers are 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-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. 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 he test head. It could be applied in production inspection and acceptance inspection to replace low accurate Leeb hardness tester.
Technical Parameter Preliminary test force:10 kgf Total test force: 60 kgf, 1000 kgf, 150 kgf Test head: 120°diamond indenter 1.588mm carbide alloy ball Indication Error: complying with ISO 6508 and ASTM E18 Repeatability Error: complying with ISO 6508 and ASTM E18 Test Resolution: 0.5HR Application range: common metal including iron and steel, cooper, aluminum.
