Productomschrijving
Usage Range
The Brinell hardness tester that shows the largest indentation among all the hardness tests is able to reflect
the comprehensive features of the material , and the test is unaffected by the organization micro-dioptre
and the compositional unevenness of the speciment ;and hence it is a hardness testing with high precision.
The Brinell hardness test is widely used in such industrial fields as metallurgy , forging , casting , unhardened
steel and nonferrous metals industries, as well as in the laboratories, universities , colleges and s-cientific
research institutes.
 
Mains Features
DHB-3000 Electronic Brinell Hardness Tester is a unified product combining the precise mechanical structure
with the computer control by means of the mechanical and electrical circuit system, and so it is the more
advanced brinell hardness tester in today’s world. The instrument adopts the motorized test force application
without weight blocks, and uses 0.5‰ accuracy compression sensor to feedback the information and the
CPU control system to automatically compensate the test force lost during the testing. The test force and
the load dwell time can be directly set pressing the selected keys on the touch-keyboard, with reliable
repetition, precise reading and easy operation.
