Product Description
Semi-Automatic Digital Vickers Hardness Tester
HVT-30XY Automatic Vickers Hardness Tester is integrated with several new technologies such as optical imaging, mechanical displacement, electronic control, digital imaging, image analysis, computer processing and so on. It controls the Vickers hardness tester and automatic test table by the computer, and displays the indentation image on the computer screen.

3. Modular design, simple maintenance
4. With hardness conversion function, from HV hardness value can covert to HR, HB, HK, etc.
5. With HV/HK test function
6. According to different visual habits of the operators, the strength of the light source can be adjusted. To avoid the visual fatigue for long time operation.
7. Industrial digital touch screen can direct display hardness value, conversion hardness, testing method, testing force, dwell time, test number and testing process.
8. One-time casting iron molding shell ensure structure more stable; Adopted car painting technology, pure white color looking more decent; High scratch resistance capability, used for years still brightness like new.
Application:
- Widely used to test the hardness of all kinds of metal materials (steel, nonferrous metals, tinsel, cemented carbide, sheet metal, etc.)
- surface layer / coating (Carburization, nitriding, decarburization layer, surface hardening layer, galvanized coating, etc.)
3) Glass, chip, ceramic, plastic and rubber, etc.
