HR-150A Instrument Description:
●Hardness is one of the important criteria of the mechanical functions of materials, and the hardness test is the important way to judge the quality of the metallic materials or parts.●As the metallic hardness has mutual correspondent relations with other mechanical functions, the majority of the metallic materials can calculate the other mechanical functions such as the strength, the fatigue, the evolutionary change and the degree of being worn out,which can be approximately inferred from the hardness shown by the test.
●HR-150A is an effective manual Rockwell testing machine with high accuracy, reliability and durability, it is applied at the workshops and measurement departments for determining the Rockwell hardness of the ferrous and non-ferrous metals.
●HR-150A analogue gauge resolution is 0.5HR, it is useful to improve the reading accuracy than traditional 1HR resolution.
●HR-150A force knob adopts the metal material to replace the plastic, it improves the instrument using-life a lot.
●HR-150A loading, dwell and unloading is buffering by oil pump, it eliminate the operator’ s tiredness.
●HR-150A indenter protector is available to improve the using lifetime of indenter.
