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 tolerance ＜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.
On-site testing the hardness of large pipes and shafts accurately on-site.
Anvils testing various dimensions and shapes work piece by using different anvils.
Application Chain fastened around the work piece before the force is applied.
Relevant Standards Comply to standard ISO 6508 and ASTM E18, E110.
Indenter Indention inspected by standard Rockwell hardness tester.
