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 and comfortable vision.

2. On the industrial display screen, the hardness value can be visually displayed, the hardness can be converted, the test method, the test force, the time of the charge and the number of measurements, and the test process can be intuitively understood.

3, Cast aluminum shell molding, the structure is stable and not deformed, high-grade automotive paint, anti-scratch ability, use for many years is still bright as new;

4. Our company has its own R&D, production and processing capabilities. Our machines provide parts replacement and maintenance upgrade services for life.

5, CHVS-50Z models can be achieved: observation - test - measurement of the position switch by the automatic turret

6.CHVS-50Z 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;

The main purpose and scope of application:

1. Iron and steel, non-ferrous metals, metal foils, hard alloys, metal sheets, microstructures

2. Carburizing, nitriding and decarburization layers, surface hardened layer, plating layer, coating

3, glass, wafers, ceramic materials, carbonization;
