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.
