Features
● Attracted to iron or steel surface by magnetic force; only one
side of the workpiece needs to be reached.
● The test principle and accuracy comply to standard ISO6508
and ASTM E110. Tested by National Institute of Metrology with
tolorance ＜1.5HRC, equivalent to bench hardness tester.
● Quick test, easy operation, good repeatability, high accuracy,
no sampling required.
● Tests workpieces of any shape and dimension only if there is
enough flat or cylindrical surface to fix the tester.
● Tests horizontally, slantingly and vertically.
● Used to accurately test the hardness of steel plate, steel pipe,
shaft, mould, tube, pressure vessel, large workpieces and
assembled parts, especially welding line and heat affected zone.
● The test surface of PHR-100x is small enough to test the
hardness of small machine guide rails.
● Used for production inspection and acceptance inspection,
replacing Leeb hardness testers with lower precision.
● Traceable standard hardness block.
● Indenter inspected with standard Rockwell hardness tester.
● Test force calibrated with load cells directly traceable to national
secondary benchmark.
