Equipment Overview:

1. Hardness is one of the important characteristics which indicate the mechanic performance of material, while the 

hardness testing is an important method to judge the quality of the metal material or its component parts.

2. The Motorized Superficial Rockwell Hardness Tester is adopted a mechanism to automatically load and unload the 

test force, through rotating the Load-Change Hand Wheel to exchange test force, therefore the operation for this 

instrument is very simple, easy and prompt. Besides setting zero to dial, there is no man made error. The instrument 

is with high sensitivity and stability, so as suitable for usage in workshop and testing laboratory.
