HSRD-45 automatic Rockwell hardness tester

HSRD-45

The automatic loading and unloading test force mechanism is adopted. The test force transformation is obtained by the rotation of the load changing handwheel. The operation is simple and rapid. Except for the zero setting of the dial, there is no artificial operation error. It has high sensitivity and stability. It is suitable for workshops and laboratories. Using the electric automatic loading technology, the total test force is applied, maintained and removed automatically, and the human operation error is eliminated; The spindle system adopts the non friction spindle structure, which improves the accuracy of the initial test force; The dial can directly read hrn and HRT scales; Accuracy in accordance with gb/t230.2
