Usage:

This tester can be used to determine the superficial Rockwell hardness value of steel, alloy steel, hard alloy, plated coating, carburized, nitrided and cyanided layers. The hardness value measured can be read off the show window.

■ A friction 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 enhanced.

■ A series of operations including load applying, holding and releasing can be performed automatically. Thus the errors occurred due to manually operation can be eliminates.

■ Hardness values digital display can avoid the reading errors by operator.

■ Hardness values and data processing results can be printed automatically by the printer.
