1. The optical system designed by a senior optical engineer not only provides clear images but can also be used as a simple microscope, with adjustable brightness for comfortable viewing, allowing long-duration operation without fatigue;

2. The 7-inch touchscreen display can show test methods, test force, upper and lower limits of hardness values, measured indentation length, hardness values, test force holding time, number of measurements, and allows input of year, month, and date, as well as test results and data processing;

3. The system comes with a built-in calibration function, allowing manual adjustment of input errors to calibrate the instrument for each test force;

4. Optical system brightness adjustable range: 0-100;

5. Can store up to 100 sets of test data, displaying the average value and number of tests on the main interface;

6. Test force units can be manually selected and converted, with conversion units: (Kgf, N);

7. The main interface can display up to 4 conversion scales simultaneously and switch among national standards, American standards, and international standards, with a total of 18 conversion scales: HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HV, HK, HBW;

8. Both objectives can directly measure hardness;

9. Equipped with diagonal length memory function, automatically remembers diagonal length after shutdown, allowing direct measurement upon startup without resetting;

10. Measurement scales can be converted to HK Vickers hardness;

11. Test data can be directly exported via USB;

12. Upper and lower measurement limits can be set and displayed on the main measurement interface;

16. Our company has the capability for independent research, design, production, and processing, and our machines come with lifetime parts replacement and maintenance upgrade services.


1. Metal Materials

Metal materials are one of the most widely used fields for Vickers hardness testing. By testing the hardness of various metal materials, one can understand their mechanical properties, processing performance, and service performance. For example, in the steel industry, the Vickers hardness tester is used to measure the hardness of steel, thereby controlling product quality and optimizing production processes.


2. Non-Metal Materials

In addition to metal materials, the Vickers hardness tester is also widely used for testing the hardness of non-metal materials. For example, in the plastics industry, the Vickers hardness tester is used to determine the hardness of plastics, thus controlling the quality and performance of products. Moreover, the Vickers hardness tester can also be used to test the hardness of materials such as ceramics and glass.


3. Composite Materials

Hardness testing of composite materials is also an important application area for the Vickers hardness tester. Composite materials consist of multiple materials, and their hardness testing needs to consider the properties and distribution of different materials. Testing with a Vickers hardness tester allows one to understand the hardness and internal structure of composite materials, thereby evaluating their mechanical properties and durability.


ASTM E384 “Standard Test Method for Microindentation Hardness of Materials”


ISO 6507 “Metallic materials -- Vickers hardness test”

The Vickers hardness tester uses a diamond square pyramid indenter with an included angle of 136°, which is pressed into the material surface under a selected test force (usually 49.03 to 980.7 N). After maintaining the force for a specified time, the test force is removed. Then, the length of the diagonals of the indentation is measured under a microscope, and the Vickers hardness value is calculated using the formula HV = 0.1891 × F / d² (where F is the test force and d is the average length of the indentation diagonals).


The core principle lies in the geometric similarity of the indentation, making the test results independent of the test force, thereby allowing accurate measurement over a wide range from very soft to very hard materials. Depending on the testing requirements, Vickers hardness testers are also classified into low-force type (<49.03 N) and microhardness type (<1.961 N), suitable for testing special samples such as thin layers, coatings, or metal foils.
