DIGITAL ROCKWELL HARDNESS TESTER MODEL: HRS-150
HRS-150 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, aluminium alloy, bearing steel, carburized steel sheet, etc.
