ASTM E18 Rockwell Hardness Test Digital Rockwell Testing Machine


Application Fields:

1. Quality control of Industrial production (machinery manufacturing, metallurgy plants, etc.)

2. Research & Inspection of Inspection Institution and universities laboratories.

3. Ferrous and nonferrous metals, Hardened steel, tempered steel, annealed steel, hardened steel, sheet of various thicknesses, carbide materials, powder metallurgy materials, hardness and thermal spray coating.

Sheet metal, thin-walled pipe, hardened steel, and small parts of hardness.



1. Nose mounted indenter allows access to awkward to reach test points ( ring shape material, tubular material, etc). Minimum working diameter is 25mm.

2. With Rockwell and superficial Rockwell testing function.

3. Closed loop force application, load cell instead of dead weights, no need to install weights, working directly after connect with electric power.

4. Touch-screen interface, English language, all test data can show on screen directly.

5. Semi-automatic type, premier test force load by manual, then mian load force loading by motor (loading main force, dwell, unload automatically), greatly improved working efficienty.

6. All Rockwell scale, test result / hardness value (high, medium and low hardness value) can be automatically calibrated on screen.

7. Test force automatic correction, improve the accuracy of a force of magnitude

8. Operator can set up a password for the machine to protect setup parameters; Safely keep test informations and setted parameters.

9. Test data can export to U disk in EXCEL format, for long time keep and easy editing and processing.

10. Machine adopted modular design, easy maintenance
