Model HBRV-187.5 Motorized Brinell, Rockwell & Vickers Hardness Tester

Model HBRV-187.5 Motorized Brinell, Rockwell & Vickers Hardness Tester

 

Main Features:

Model HBRV-187.5 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, rotate the Load-Change Hand Wheel to change values of testing force, therefore the operation for this instrument is simple, easy and quickly. Beside set zero to the dial, there is no man-made error for operation. The present instrument is with high sensitivity and stability, so as fit for usage in workshop and testing laboratory.
