Main functions and features of the machine:

1. The optical system designed by senior optical engineers not only has clear images, but can also be used as a simple microscope. The brightness is adjustable, the vision is comfortable, and it is not easy to get tired after long-term operation;

2. The industrial display screen can display the test method, test force, measured indentation length, hardness value, test force holding time, and number of measurements;

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

4. Our company has the ability to independently develop, design, produce and process, and our machines provide lifetime parts replacement and maintenance upgrade services;

5. The CHV-30Z model can input the measured indentation length on the button to obtain the hardness value;

6. The CHV-30Z model can achieve: observation-test-measurement position switching is completed by the automatic turret;

Main uses and scope of application:

1. Steel, non-ferrous metals, metal foil, cemented carbide, metal sheet, microstructure, carburization;

2. Carburizing, nitriding and decarburizing layers, surface hardening layers, electroplating layers, coatings, heat treatment;

3. Glass, wafers, ceramic materials;
