Main functions and features:

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

2. The 7-inch touch screen can display the test method, test force, upper and lower limits of hardness value, measured indentation length, hardness value, test force retention time, measurement times and can enter year, month, date, test results and data processing Wait;

3. The system comes with a calibration function, and each test force can be manually adjusted to input the error calibration instrument;

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

5. It can store up to 100 sets of test data, and display the average value and test times data on the main interface;

6. The test force unit can be manually selected for mutual conversion, the conversion unit is: (Kgf, N)

7. The main interface can display 4 conversion scales at the same time, and can switch between national standards, American standards and international standards. A total of 18 measurement scales can be converted: HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK , HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HV, HK, HBW;

8. Both objective lenses can directly measure the hardness,

9. The upper and lower limit measurement range can be set and displayed on the main measurement interface;

10. Test data can be directly exported via USB;

11. The measuring scale can be converted into HK Knoop hardness;

12. The operating system can be converted between Chinese and English;

13. Optional built-in printer, test data can also be output to U disk via USB for storage and analysis;

14. The cast aluminum shell has a stable structure without deformation at one time, and the pure white car paint has a high grade, strong scratch resistance, and it is still bright as new after many years of use;

15. Our company has the ability to develop, design, produce and process by ourselves. Our machines provide parts replacement and maintenance upgrade services for life

Main application scope:

1. Steel, non-ferrous metals, metal foil, cemented carbide, metal sheet, microstructure, carbonization;

2. Carburizing, nitriding and decarburizing layer, surface hardening layer, electroplating layer, coating, heat treatment;

3. Glass, wafers, ceramic materials;
