1. Hardness is one of the important mechanic characteristics of the material while the hardness testing
is the most quickly and economic testing method,as well as an important method to judge the quality of
the metal material or its component parts. The mechanic characteristics of most metal materials such
as the strength, tiredness, wriggling and wearing out can be tested out approximately through its
hardness testing.
2. The Motorized Brinell Rockwell & Vickers Hardness Tester, a multi-functional hardness tester with
Brinell, Rockwell &Vickers 3 kinds of testing methods and 7 steps testing force will meet the needs of
many kinds of hardness measurement. The instrument is adopted automatic shifter to load, dwell and 

unload testing force, therefore the operation for this instrument is simple, easy and quickly.
