ASTM E18 Clamp Rockwell

Portable Hardness Tester with Open Size 200 x 100mm

Download Technical Data: 

Brief Introduction:

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.
