Features:
● Used for testing the hardness of large pipes and shafts accurately on-site.
● 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.
● Chain fastened around the workpiece before the force is applied.
● Reliable stability,good repeatability and high accuracy.
● Tests the hardness of cylindrical workpieces such as pipes, shafts, rollers etc.,tests on the welding line;tests in segments.
● Used for manufacturing inspection and acceptance inspection to replace Leeb hardness tester with lower accuracy.
● Traceable standard hardness block.
● Indenter inspected with standard Rockwell hardness tester.
● Test force calibrated with load cells directly traceable to national secondary benchmark
