Electronic Motorized Test Force with CPU Control Brinell
Hardness Tester DHB-3000
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.
