Usage:

This tester is a necessary instrument widely used in the field of machine building, metallurgy and measurement department, 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 the instrument instead of conventional type. As a result, the accuracy of preliminary test force has been greatly increased.

A unique automatic zeroing dial gauge is incorporated in this instrument for measuring the depth of indentation so as to eliminate the human error in the procedure of zero setting.

A series of operations involving applying, holding and releasing of total test force is performed automatically. That thoroughly eliminates human error in those operations.
