ASTM E18 Clamp Rockwell Portable Hardness Tester with Open Size 200 X 100mm
PHR-8-4 C clamp Rockwell hardness tester was designed according to the basic principle of Rockwell hardness testing standard ASTM E110.
C clamp Rockwell hardness tester applies part clamping structure and similar reading system as micrometer, so it is prior to small type for its good stability, repeatability, accuracy.
It consists of C- shape frame, screw arbor, and test head. Can test flat or curve parts as long as the parts could be clamped and the test surface erects the test head. Mainly applied in production quality inspection to replace low accurate Leeb hardness tester.
Preliminary test force: 10kgf
Total test Force: 60kgf, 100kgf, 150kgf
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
