Features:
- Manual turret shifting between indenter and objective lens
- Standard 8-level force, from 10gf (0.098N) to 1kgf (9.8N), 2Kgf (19.6N) is optional, users can customize the test force.
- After measuring the indentation diagonal length, the system will automatically calculate and display the hardness value.
- Both two objectives can be used to test hardness value.
- Based on the standard block of different forces, the hardness value can be corrected automatically.
- 8” Touch-screen interface, easy to operate, multi-language is available.
- Testing data can be saved into U disk directly in EXCEL format, which is convenient for easy editing and processing (Optional USB interface).
- The information of test samples, operator etc. can be input and saved.
- Password can be set to protect setting parameters.
- Measured hardness value can be automatically converted to other scales.
- Modular design, easy maintenance, large space for sample.
- Optional image measuring system can be equipped with this hardness tester so as to connect with computer for automatic operation.
Application:
Heat treatment, carbide, quench hardened layer, the surface coating layer, steel, non-ferrous metal and small and thin shape parts, etc.
