1. Simple Introduction
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.
1, Lever Loading, manual operation, durable and reliable.
2, No friction spindle, high precision test force.
3, Precision hydraulic buffers, steady load.
4, Dial display the hardness value, HRA, HRB, HRC, and can choose other Rockwell Scale.
5, Accuracy according to GB / T230.2, ISO 6508-2 and American ASTM E18 standard.
