Description:

It won the national quality silver medal prize, it is one type of practical semiautomatic hardness measuring instrument. It can be widely applied in the factories, scientific research institutes and laboratories of colleges, for determining the Rockwell hardness of ferrous, non-ferrous metals, non-metal materials and their finished parts. Features 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.
