HR-45A Manual Superficial Rockwell Hardness Tester for Metals Alloy Steel
Introduction:
HR-45A surface Rockwell hardness tester can be used to determine steel, alloy steel, cemented carbide and metal surface treatment - such as carburizing, nitriding. The surface Rockwell hardness value of the electroplating layer is an indispensable hardness measuring instrument in the mechanical metallurgy and metrology departments.
Application range:
Determination of surface Rockwell hardness of ferrous metals, alloy steels, cemented carbides and metals after nitriding, cyanidation, carburizing, electroplating, etc.;
It is suitable for hardness testing of small parts samples;
Main features:
1. Lever loading, manual operation, precise and durable, high test efficiency;
2. Adopt universal boom (patent) to realize free connection between weight system and load lever;
3. Easy installation and low failure rate;
4. The dial can directly read the HEN and HRT scales (other scales of Rockwell on the surface are optional);
5. Accuracy conforms to GB/T230.2 ISO6508-2 and American ASTM E18 standard;
