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 metal hardness tester is usually used for manufacturing inspection and acceptance inspection to replace Leeb hardness tester with lower accuracy.
