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. Due to the hardness of the metal is correspondent to its mechanic characteristics, and so its mechanic characteristics such as the strength, tiredness, wriggling and wearing out can be calculated out approximately through its hardness testing.
2. The Motorized Rockwell Hardness Tester is adopted a mechanism to automatically load and unload the test force, rotated 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.
