. A frictionless loading shaft mechanism is adopted in this instrument instead of conventional type and the application of preliminary test force is controlled by a magnetic clutch, so that the accuracy of preliminary test force is greatly increased.
. A series of operations including applying, holding and releasing of total test force is performed automatically. That completely eliminates human error in those operations.
. Reading error by operators can be avoided thoroughly as the measured hardness values are digitally displayed.
. The measured hardness value and data processing result concerned can be recorded automatically by the recorder.
