Metallurgy Forging Casting Unhardened steel and Nonferrous
Metals Brinell Hardness Tester XHB-3000
Usage Range
The Brinell hardness test 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
organizational 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 scientific
research institutes.
Main Features
XHB-3000 Digital Brinell Hardness Tester is a unified product
combining the precise mechanical
structure with the computer control by means of the optical,
mechanic and electrical circuit
system, and so it is the most 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 indentation
is directly measured on the
instrument through the microscope, and the LCD screen indicates the
diameter, the hardness
value, and 17 different hardness testing comparison tables as well
as the HBW range
automatically shown under the present presetting. It is possible to
preset the load dwell time and
the intensity of the light on the window page ,and design a F/D2
selection table to facilitate the
operation of the user. The instrument is completed with a RS232
serial interface connected with a
PC for final read-out, the printer and the date storage.
