HBS-3000CM color screen digital display Brinell hardness tester is a high-tech product of opto-mechanical integration. The
hardness tester has a novel shape, good reliability, operability
and intuitiveness. It is a new type of precision mechanical
technology and optoelectronic technology. Brinell test equipment.
The machine adopts computer software programming, photoelectric
sensing and other technologies. Through virtual key input, choose
the test method and hardness to compare, store, etc., use a
5.6-inch true color touch LCD large screen display and control, on
the LCD large screen display can display the test method, test
force, measure indentation length, hardness Value, test force
holding time, test force and hardness measurement range,
measurement times, qualified judgment, and can input year, month,
date, test results and data processing, etc., output through
printer, USB interface and computer network.
Brinell hardness test is mainly used for hardness measurement of
cast iron, steel, non-ferrous metals and soft alloys, etc. In
addition, it can also be used for hardness measurement of some
non-metallic materials such as hard plastics and bakelite. It is
suitable for factories, workshops, laboratories, colleges and
universities and scientific research institutions.

4. How do you read a Brinell microscope?
Manual reading is easy and straightforward. You look through the
lenses, focus the optics, position in the lens on the impression
and read the result in mm. The result in mm is then converted to
HBW (Hardness Brinell) by looking up the mm measurement and the
table provides the hardness.
5. What is the difference between Brinell and Rockwell hardness
test?
The Brinell hardness testing uses a 10mm hardened steel ball, while
the Rockwell test uses either a much smaller steel ball (<4mm)
or a diamond cone, depending on the material being tested. The
Rockwell test measure the depth of the indentation, while the
Brinell test measures the width of the indentation.
6. What indenter is used for Brinell test?
spherical indenter
In the Brinell hardness test, an optical method, the size of
indentation left by the indenter is measured. In contrast to the
likewise optical Vickers method,which involves a pyramid-shaped
indenter being pressed into a specimen, the Brinell method uses a
spherical indenter.
7. How do you find the Brinell hardness number?
The Brinell hardness number (BHN) is calculated by dividing the
load applied by the surface area of the indentation. Figs.
6.72–6.74 show some of the Brinell hardness test sites.
8. Is standard for Brinell hardness testing?
ISO 6506-1:2014 specifies the method for the Brinell hardness test
for metallic materials. It is applicable to both fixed location and
portable hardness testing machines.
9. What is a Brinell microscope?
This instrument is a low-power hand-held microscope for measuring
the diameter of a Brinell hardness indentation. The Brinell
hardness value is calculated from the indentation diameter
measurement, ball diameter and applied force. The Brinell hardness
test was developed around 1900 for testing the hardness of metals.
10. How do you the Rockwell and Brinell tests actually measure
hardness?
Brinell hardness is determined by forcing a hardened steel or
carbide ball of known diameter under a known load into a surface
and measuring the diameter of the indentation with a microscope.
11. Why Brinell and Vickers hardness test results show similarities
Mcq?
Why Brinell and Vickers hardness test results show similarities?
Explanation: Brinell test indenter is made of hardened steel.
Vickers test indenter is made of diamond. These give geometrically
similar indentations so the similar results.
