RT-1001A HR-150A Manual Rockwell Hardness Tester
Product Details：
Equipment Overview:
The hardness is one of the important criteria of the mechanical functions of the materials, and the hardness test is the important means to judge the quality of the metallic materials or parts, As the metallic hardness ha 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 can be approximately inferred from the hardness shown by the test.
The manual Rockwell hardness fester is a popularly-used hardness testing instrument to measure the Rockwell hardness of the materials. The speed of loading the test force is regulated by the buffer whereas the change of the test force is made by rotating the carriage-changing hand-wheel. The operation of the present instrument is simple, its functions are stable, and its use is, therefore, widely spread.
