ASTM E18 Clamp Rockwell Portable Hardness Tester with Open Size 200
X 100mm
Technical Data Download: iqualitrol portable rockwell hardness tester PHR-8-4
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.
