Features:
It's suitable to determine the Rockwell & Superficial Rockwell hardness of ferrous metals, alloy steel and hard alloy, as well as treated layers of metal
surface, such as carburized layer, nitrided layer and electroplated coating, etc. It's especially suitable to determine heterotypic workpiece.
- Test force closed-loop control
- Automatic tracking and testing, no test error caused by deformation of frame and workpiece
- Automatically clamp the workpiece, suitable for testing of abnormal shape workpiece, no need to apply preliminary test force by hand
- High accuracy optical grating displacement measuring system
- Large LCD display, menu operation, complete functions (data processing, hardness conversion between different hardness scales)
- RS232 data interface
- Upper-computer is optional (equipped with special software)
- Precision conforms to GB/T 230.2, ISO 6508-2 and ASTM E18
