Features

1. Using 8-inch touch screen and high-speed ARM processor, the display is intuitive, the human-computer interaction is friendly, and the operation is simple; the calculation speed is fast, the database is massively stored, the data is automatically corrected, and the data line report is provided;

2. The fuselage is made of high-quality cast iron by one-time casting, combined with the car paint treatment process, the appearance is round and beautiful;

3. Equipped with automatic turret function, high-definition measurement and observation-dual objective lens combination, combined with the high-definition micrometer eyepiece with built-in length encoder, realizes one-key measurement of indentation diagonal, and better reduces human operation interference and reading error;

4. Convenient numerical control system, which can automatically convert the unit of the full hardness scale;

5. The maximum and minimum hardness values ​​can be set. When the test value exceeds the set range, an alarm sound will be issued;

6. With the software hardness value correction function, the hardness value can be directly corrected within a certain range;

7. With database function, the test data can be automatically saved in groups, each group can save 10 data, and more than 2000 data can be saved;

8. It has the function of displaying the hardness value curve, which can visually display the change of the hardness value;

9. CCD image processing system, and optional Knoop indenter for Knoop hardness measurement;

10. Configure a wireless Bluetooth printer, and output data through RS232 and USB interfaces;

11. The accuracy conforms to GB/T4340.2-2018 ISO6507-2 and American ASTM E384.
