Color Touch Screen Digital Shb-3000d Brinell Hardness Tester¹

Product Description 1, Vexus SHB3000D differs from like products is the close loop loading system, key panel and touch screen double input methods, blue tooth transferring technology and digital measurement indentation technology.2, High accuracy close loop loading sensor replace traditional weights loading method, to realize automatic loading, dewell and unloading, makes easier installation and better measurement accuracy.3, Equips with 5.2" color touch screen with innovative interface design, makes force selection, dwell time setting, scale conversion and data reading, transferring, printing more convenient and fast.4, One touch operation of indentationmeasurement by high resolution objective, largely eliminate human error and avoid annoyance to check indentation comparison table.5, Auto hardness conversion from Brinell scale HBW to HK, HV, HRA, HRB, HRC, superficial rockwell scales, etc.6, Equips with Bluetooth Device, optional Bluetooth printer and computer acceptor is available to realize wireless printing and data transferring.When selecting a hardness tester for your application, it is important for you to consider the following:A, Choose the correct test method based on the application.Plan to use the highest test force and largest indenter possible. Consider the effects of the shape and dimensions of your test sample.B, Verify the test results meet your requirements for accuracy and repeatability. There are significant differences between levels of performance within each classification of tester. A difficult job on one tester could be very simple and fast on another.Answer these key questions:1, What kind of hardness scale to be used?2, What is the material to be tested, and is this material suitable to the type of test method you are considering?3, How large is the part, component or specimen to be tested?4, Is the test point difficult to reach?5, What is the quantity of testing that will be done?6, How accurate does your test result need to be?7, What is your budget?8, What is the required return on investment and do you have ways to measure reductions in costs- yields, throughput, operator efficiency?9, What testing problems have you experienced in your current method?10, How knowledgeable are the users of the tester?Principle of Brinell TestThe 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.Specifications:Product NameDigital Brinell Hardness TesterModelSHB-3000DCode#831-121Testing Force62.5Kgf, 100Kgf, 125Kgf, 187.5Kgf, 250Kgf, 500Kgf, 750Kgf, 1000Kgf, 1500Kgf, 3000Kgf612.9N, 980N, 1226N, 1839N, 2452N, 4900N, 7355N, 9800N, 14700N, 29400NTesting Range(8~650) HBWHardness Display5.2" Touch Screen LCD DisplayMagnification of Microscope20x Digital MicroscopeMax. Height Of Specimen225mmInstrument Throat135mmPower SupplyAC220V/50Hz;110V/60HzDimension(LxWxH)893 x720 x747mmGross/Net Weight160Kg/130KgExecution StandardISO 6506 , ASTM E10 - 12 , JIS Z2243 , GB/T 231Accuracy of Brinell Hardness TestingHardness RangeMax. ToleranceRepeatabilityHBW≤ 125< 3.5 %< 3.5 %125 < HBW≤225< 2.5 %< 3.0 %HBW >  225< 2.0 %< 2.5 %Standard Delivery:Standard DeliveryCode#Standard DeliveryCode#Standard DeliveryCode#Instrument Main Body831-121?5mm Ball Indenter831-421Power Cable831-80120x Digital Microscope831-221?2.5mm Ball Indenter831-431Accessories Box831-901Hardness Block HBW/3000/10831-601? 200mm Flat Anvil831-551Anti-dust Cover831-911Hardness Block HBW/750/05831-611? 60mm Flat Anvil831-501Level Screw831-931?10mm Ball Indenter831-411? 55mm V-shape Anvil831-521Instrument ManualSHB-3000D
