DR-187.5F Touch Screen Digital Display Brinell, Rockwell and Vickers Hardness Tester

The touchscreen digital display Brinell, Rockwell and Vickers hardness tester has a novel appearance, complete functions, convenient operation, clear and intuitive display, and stable performance. It is a high-tech product integrating optics, mechanics and electronics. It can perform Brinell, Rockwell and Vickers hardness tests and is a multifunctional hardness tester with 23 measurement scales, meeting various hardness testing requirements. It features high testing accuracy, simple operation, high sensitivity, and ease of use, with stable readings. It is equipped with an internal printer and can be connected to a computer via an RS232 data cable or a USB flash drive to export measurement reports. The large-screen LCD touch screen display interface is rich in content and easy to operate.

Main features of the instrument:

1. The optical system designed by optical engineers not only provides clear images but can also be used as a simple microscope. The brightness is adjustable, providing a comfortable visual experience and reducing fatigue during long-term operation.

2. The 7-inch LCD touch screen can directly display hardness values, conversions, test methods, test forces, brightness, holding time, measurement times, statistics, and test time, making the test process clear and intuitive.

3. The system has a built-in calibration function, allowing manual adjustment to correct input errors.

4. When testing curved surfaces, it automatically corrects according to the standard radius of curvature.

5. The adjustable range of the optical system's brightness is 0-100.

6. It can store 100 sets of test data, allowing for real-time viewing, deletion of current data, or clearing all test data.

7. The test force unit can be manually selected and converted, with conversion units of (Kgf, N).

8. It can simultaneously display the maximum value, minimum value, average value, test times, and sample name (sample number can be input).

9. The main interface can simultaneously display 4 conversion scales and can switch between: Chinese National Standard (GB), American Standard (ASTM), and International (ISO) standards, with a total of 21 measurement scales: HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRK, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HK, HBW, HS, HBS, HV, Rm (tensile strength), MPa (pressure).

10. It has a diagonal length memory function. After shutdown, the diagonal length is automatically remembered, and measurement can be directly performed upon startup without the need for a second zeroing.

11. It can set upper and lower limit measurement ranges, which are displayed on the main measurement interface, and automatically prompt an alarm for non-conforming values.

12. The operating system supports 13 languages and can be freely switched: Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, Vietnamese.

13. It is equipped with Brinell, Rockwell, and Vickers test methods and 8 test forces, meeting various hardness testing requirements.

14. It is equipped with an internal printer, and test data can also be output to a USB flash drive for storage and analysis.

15. The cast aluminum shell is formed in one piece, ensuring stable structure without deformation. The pure white automotive paint finish is of high grade, with strong scratch resistance, and remains bright as new even after years of use.

16. Our company has the ability to independently research, design, and produce. We provide lifetime parts replacement and maintenance upgrade services for our machines.

Main uses and application scope of the instrument:

1. Testing the Brinell, Vickers, and Rockwell hardness of ferrous metals, non-ferrous metals, and hard alloys.

2. Testing the Brinell hardness of castings, annealed steel, normalized steel, non-ferrous metals, and soft alloys.

3. Testing the Rockwell hardness of quenched and tempered materials.

4. Testing the Vickers hardness of nitrided layers, ceramics, thin plates, metal sheets, electroplated layers, and small parts.
