Dolphin Nose Twin Rockwell Hardness Tester With Rockwell and Surface Rockwell

With Rockwell and superficial Rockwell test scale;
Test force: 15 / 30 / 45 / 60 / 100 / 150kgf (initial test force: 3 / 10kgf)
Automatic testing process: Automatic loading - Dwell - Unloading, and automatic display hardness value.
With USB interface, test data can save to U-flash directly in Excel format.
Easier calibration function ensure high accuracy of test result.
Availability:
  • RSR-45/150NT

  • EBP INSTRUMENTS

  • Shanghai / Shenzhen / Ningbo

  • 150 sets per month

  • TT in advance

  • 1 set

Features:

1. With Rockwell & superficial Rockwell testing function.

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

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

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

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

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

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.


Dolphin Nose Indenter (Nose mounted indenter) allows access to awkward to reach test points:

1) Ring shape material

2) Tubular material

3) Screw corner

4) Bearing corner, etc.
