2. The z-axis rises and falls automatically. After the sample is put in, it rises automatically and begins to impress; Electric loading closed-loop control, automatic loading;

3. each gear of force is automatically compensated, and the accuracy of force value (at 3000kg) is increased by one order of magnitude to one thousandth;

4. automatic turret, automatic conversion of pressure head position and measurement position;

5. the main machine is equipped with three indenters (10, 5, 2.5mm) and double objective lenses (double magnification 20x/40x). For large and small Brinell indentations, there is no need to replace the indenter and measuring objective lens

6. when measuring indentation, it is fully automatic focusing without manual adjustment;

7. according to the standard blocks with different force values, the hardness value is automatically corrected;

8. large sample space, where large samples can be placed; It can be used immediately after startup without installing weights and debugging; Touch screen interface, easy to operate, any language version;

9. more sample and test information can be set and saved; Set password protection setting parameters;

10. the product is designed and produced by itself, has independent intellectual property rights and software copyright, and can be customized and upgraded for a long time.
