1. Specially designed head horizontally extends, can measure coronal, tubular and other parts that general hardness cannot be measured. The minimum inner diameter measured is 15mm;
2. Automatic "fool" type operation, press a key to get results without artificially preload, effectively prevent human error;
3. Touch screen interface, easy operation, with any language version;
4. Boot and can be used, no need to install counterweight, without installation
5. The electric load, closed-loop control
6. Test force automatic correction, the force accuracy improves a magnitude
7. All Rockwell scale, high, medium and low hardness values automatically corrected
8. Set up a password to protected setup parameters; keep more samples and test information
9. U disk save measurement data to EXCEL format for easy editing and processing
10. Modular design for easy maintenance
