HBRVU-187.5 Brinell, Rockwell & Vickers Optical Hardness Tester
Product Detailed
this machine Can measurese the steel, have the color metals, the thin slice of IC, thin plastics, metals thin slice .

HBRVU-187.5 Brinell, Rockwell & Vickers Optical Hardness Tester

 with numerous testing forces and various indenters adopts rotational testing power transforming mechanism and optical measurement indicating system applied to test the Brinell, Rockwell and Vickers hardness of metal materials. It is the multi-functional hardness tester able to test the diverse hardness of materials with different testing methods to meet the requirements of multiple hardness tests for users.


Main purpose and the scope of the application:

Applicable to quenched steel, surface-quenched steel, alloy steel, cast iron, nonferrous metals, all kinds of quenched and annealed steel, hardened steel sheet, also suitable for soft metal, surface  heat treatment and chemical heat treatment.
