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 large LCD screen of the industrial display screen can display the test method, test force, measured indentation length, hardness value, test force retention time, measurement times and can enter the year, month, date, test results and data processing, etc.;

3. The cast aluminum shell is formed at one time, the structure is stable and does not deform, the car paint grade is high, the scratch resistance is strong, and it is still bright as new after years of use;

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

5. CHVS-5Z model can measure the actual length and directly confirm the hardness value;

6. The CHVS-5Z model can realize: the position switch of observation-test-measurement is completed by automatic turret;

7. Equipped with a large LCD screen; the large LCD screen display is convenient for observation, and the test conditions and test process are intuitive and clear;

8. Optional built-in printer; direct printing of test results and test data;

Main purpose and scope of use：

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;
