Main features of the instrument:

1. The optical system designed by senior optical engineers not only has clear images, but can also be used as a simple microscope. The brightness is adjustable, the vision is comfortable, and it is not easy to get tired after long-term operation;

2. The 8-inch LCD touch screen can intuitively display the hardness value, conversion hardness, test method, test force, brightness, dwell time, number of measurements, statistical data, test time and other test processes;

3. The system has a calibration function, and the input error can be manually adjusted to calibrate the instrument;

4. When testing the curved surface, it is automatically corrected according to the standard curved surface radius;

5. The adjustable brightness range of the optical system: 0-100;

6. It can store 100 sets of test data, and the test data can be viewed at any time, and the current data can be deleted or all test data can be cleared;

7. The test force unit can be manually selected to convert to each other, and the conversion unit is: (Kgf, N)

8. It can simultaneously display: maximum value, minimum value, average value, number of tests, test block name (test block number can be entered);

9. The main interface can display 4 conversion scales at the same time, and can switch between: national standard (GB), American standard (ASTM) and international (ISO) standards, a total of 21 measurement scales can be converted: 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. With diagonal length memory function, the diagonal length is automatically memorized after shutdown, and can be measured directly after startup without secondary zeroing.

11. The upper and lower limits of the measurement range can be set and displayed on the main measurement interface. Unqualified values will automatically prompt an alarm;

12. The operating system has 13 languages, which can be switched at will: Chinese, English, Russian, German, French, Spanish, Portuguese, Turkish, Czech, Japanese, Korean, Thai, and Vietnamese;

13. It has three test methods: Brinell, Rockwell, and Vickers, and thirteen levels of test force, which can meet various hardness test requirements;

14. It is equipped with a built-in printer, and the test data can also be exported to a USB flash drive for storage and analysis via USB;

15. The one-time molding structure of the casting shell is stable and does not deform. The pure white car paint is of high grade and has strong scratch resistance. It is still bright as new after years of use;

16. Our company has the ability to independently develop, design, produce and process. Our machines provide lifetime parts replacement and maintenance upgrade services;

Main uses and scope of use of the instrument:

1. Determine the Brinell, Vickers, and Rockwell hardness of ferrous metals, non-ferrous metals and cemented carbides:

2. Brinell hardness of castings, annealed steel, normalized steel, nonferrous metals and soft alloys;

3. Rockwell hardness of heat-treated materials such as quenching and tempering;

4. Vickers hardness of nitrided layers, ceramics, thin plates, metal sheets, electroplated layers, and tiny parts;
