PHR Chain Clamp Rockwell Hardness Tester can test the hardness of cylindrical work pieces 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 tolerance less than 1.5HRC, equivalent to bench hardness tester. So this kind of Rockwell hardness testing machine is usually used for manufacturing inspection and acceptance inspection to replace Leeb hardness tester with lower accuracy.
