Video-Eye Hardness Measuring System is a set of video measurement device to update the traditional optical Brinell hardness tester, Vickers hardness tester, Micro Vickers hardness tester, and Knoop hardness tester as vision hardness tester, it is composed of Eyepiece-Measuring-Camera: #823-811 and Display Monitor: #823-821.
When the optical hardness tester is equipped with this device, the
indention is displayed on the monitor #823-821 magnificately, the
indention will be observed by many inspectors simultaneously, it
makes the measurement of indention more intuitively and accurately,
and it reduces operator’s eye fatigue and error to improve the work
efficiency obviously.
It can be used to update the following models:
Digital Vickers hardness tester: HV-5 Series, HV-10 Series, HV-30
Series and HV-50 Series
Digital Micro Vickers hardness tester: HVS-1000 Series, SMHV-1000/
2000Series, etc.
Digital Brinell hardness tester: SHB-3000C
Principle of Brinell Test:
The Brinell hardness test method consists of indenting the test
material with a 10 mm diameter hardened carbide ball subjected to a
load of 3000 kg. For softer materials the load can be reduced to
1500 kg or 500 kg to avoid excessive indentation.
The full load is normally applied for 10 to 15 seconds in the case
of iron and steel and for at least 30 seconds in the case of other
metals. The diameter of the indentation left in the test material
is measured with a low powered microscope. The Brinell harness
number is calculated by dividing the load applied by the surface
area of the indentation.
The diameter of the impression is the average of two readings at
right angles and the use of a Brinell hardness number table can
simplify the determination of the Brinell hardness. A well
structured Brinell hardness number reveals the test conditions, and
looks like this, "75 HB 10/500/30" which means that a Brinell
Hardness of 75 was obtained using a 10mm diameter hardened steel
with a 500 kilogram load applied for a period of 30 seconds.
On tests of extremely hard metals a tungsten carbide ball is
substituted for the steel ball. Compared to the other hardness test
methods, the Brinell ball makes the deepest and widest indentation,
so the test averages the hardness over a wider amount of material,
which will more accurately account for multiple grain structures
and any irregularities in the uniformity of the material. This
method is the best for achieving the bulk or macro-hardness of a
material, particularly those materials with heterogeneous
structures.

Dear Visitor:
Thanks a lot for you browse our official website: www.sinowon.com
firstly.
We, Sinowon Innovation Metrology Manufacture Limited is one of
China authorized hi-tech manufacturer of metrology instrument
verified by ISO9001:2015, we are focusing to research, develop,
manufacture and export the optical measurement instruments and
hardness testing machines since year 2006. We have already
delivered and installed more than 10,000pcs of instruments to more
than 5000 customers in more than 60 countries and regions, more and
more international famous manufacturers choose us as the qualified
supplier of quality control machines, and our service engineers
have already visited USA, Canada, Mexico, Germany, Holland, France,
Poland, Hungary, Czech, Turkey, Korea, Malaysia, Thailand,
Philippine, Viet Nam, Singapore, Austria, India to install our
instruments at customers’ site.
In the past 12 years, we concentrate ourselves to manufacture the
instrument of quality control and never change our business field.
We improve the quality and accuracy every year, up to now, it is
1.4+L/200um about the accuracy of our AutoVision vision measuring
machine and it is 0.5HRC about the accuracy our iRock Rockwell
hardness tester. Because the high quality of ultrasonic hardness
tester SU-300 family, the national standard organizations SAC/TC
183 had invited us to make China national standard, the new
standard: GB/T34205-2017 and JJF14306-2013 make more customers
choose this NDT method: UCI to control the hardness of products.
As a manufacturer of quality control instruments, it is very
important on own quality control system. In order to supply the
stable quality products, we spent a lot of time and investment for
staff training and quality system establishment and improvement
every year, we also invest a lot of money to equip the
international brand new coordinate measuring machines, roughness
testers, humidity and temperature chambers, laser machines, glass
scales, gauges and blocks for our own quality control. At the same
time, Sinowon has been verified by ISO9001 quality management
organizations every year, and our products have been issued by CE
certificate for European market and Ghost certificate for Russian
market.
The industry 4.0 is coming, we have already been ready for the
challenge. Your request of precision is our mission forever, and we
will supply the timely and warm-heart support and service as usual.
Let us work together, success together.
Thanks a lot again
