PHR-1 Portable Hardness Tester Rockwell Hardness Testing Machine
With Space 25 X 25mm
Breif Introduction:
PHR-1 portable Rockwell hardness tester complies with the basic
designing principles of Rockwell hardness testing in accordance
with international standard ISO6508, American Standard ASTM E18 and
ASTM E110.
The hardness values can be read directly from the Rockwell hardness
testers after rapid and accurate operations. It can be considered
as a non-destructive testing with very small indentations. This
kind of testers can be used at site to test the finished or
semi-finished work pieces piece by piece in batches. Rockwell
hardness testers are mostly applied in the metal-processing
enterprises.
