Product Description

HBRV-187.5 Motorized Brinell Rockwell & Vicker Universal Hardness Tester

 

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 & Vicker Hardness Tester, a multi-functional hardness tester with Brinell, Rockwell &Vicker 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.
