PHR Chain Clamp Rockwell Hardness Tester which can test the hardness of cylindrical workpieces such as pipes, shafts, rollers accurately on-site. The test principle and accuracy comply to standard ISO 6508 and ASTM E110. Tested by National Institute of Metrology with tolorance <1.5HRC, equivalent to bench hardness tester. So this kind of manual Rockwell hardness tester is usually used for manufacturing inspection and acceptance inspection to replace Leeb hardness tester with lower accuracy.
Initial Test Force: 10kgf Total Test Force: 60kgf, 100kgf, 150kgf Force Applying Method: By Screw Indenter: 120°diamond cone Ф1.588mm carbide ball Accuracy: Meets the requirements of ISO6508, ASTM E 18 Resolution: 0.5HR Testing Range: HRA, HRB, HRC, etc. 15 scales. Application: All metals including iron, steel copper, aluminium, etc. |
