HR-150/45 Rockwell & Superficial Rockwell Hardness Tester
Main Features:
The dual Rockwell hardness tester integrates both standard Rockwell and superficial Rockwell functions, expanding its application range.
It adopts lever loading and manual operation, featuring high precision, durability, and efficient testing.
It is easy to use with a low failure rate.
Hardness values are read directly from the dial. For scales including HRA, HRBW, HRC, HRN, and HRT, other Rockwell standard scales can also be optional.
Its accuracy complies with the standards of GB/T230.2, ISO6508-2, and ASTM E18.
Application Range:
Standard Rockwell: Suitable for testing the Rockwell hardness of ferrous metals, non-ferrous metals, and non-metallic materials. It applies to heat-treated materials (such as quenched and tempered materials) and cemented carbides.
Superficial Rockwell: Suitable for testing the superficial Rockwell hardness of ferrous metals, alloy steels, cemented carbides, and materials after surface treatments (including nitriding, cyaniding, carburizing, oxidation, and electroplating).
