Touch Screen Brinell Digital Hardness Tester with Bluetooth Transferring and Printer

Features:

SHB-3000D is a half automatic and intelligent Brinell hardness testing machine, it adopts the load cell to replace the traditional quality weight, this innovative design makes the instrument more accurate.

SHB-3000D selection of testing force and dwell time is controlled and monitored on the front panel, it is automatic during the process of loading, dwell and unloading.

SHB-3000D adopts digital Brinell microscopes with adjustable LED illuminator, it doesn't need the operator to read the detail length of indentation, it only needs operator to aim the D1, D2 diagonal of indentation and press the length key twice above the Microscope, then the built-in computer can compute the Brinell scale and display the final testing result on LCD display automatically.

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
