Introduction
HR-150DT digital Rockwell Hardness Tester adopts novel-designed large LCD screen to display, as well as menu structure. It mainly functions are as follows:
1. Selection of Rockwell hardness scales
2. Choice of plastics Rockwell scales (special requirement, supply accord to sales contract)
3. Exchange hardness values among hardness scales
4. Output the results of hardness measurement with printer
5. RS-232 hyper terminal setting is with good reliability, excellent operation and easy watching.
Usage Range:
Hardened and surface hardened steel, hardening and tempering steel, tempered steel, cold and hard casting parts, forging parts, hard alloy steel, aluminum alloy, bearing steel, carburized steel sheet, etc.
