Detailed Description

Digital Automatic Load-cell type Brinell Hardness Tester KHB-3000A KHB-3000A Tester conforms to: ISO6506 Metallic Materials-Brinell Hardness Test ASTM E-10 Test Method for Brinell Hardness of Metallic Materials Specification: * Innovative closed-loop technology. The tester incorporates the latest load cell technology. The test load is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit. The result is highly accurate measurements at all test loads up to 0.5%. The common load overshoot or undershoot as known from traditional dead weight, or open-loop, systems is eliminated. The absence of mechanical weights not only eliminates friction problems but also makes the equipment less sensitive to misalignments caused by vibrations. * The whole weight of the tester is 50% less than the traditional dead weights type tester. * Test load selection by keyboard and LCD screen. No need of handling heavy weights or cleaning the messy oil. * Fully automatic test cycles. The hardness Tester features a fully automatic test cycle, load application, holding, unloading, is performed fully automaticly. This greatly improves reproducibility of test results since operator influence is eliminated. * Selectable dwell times by screen. The indenter, load, and other test informations are showing clearly on the large LCD screen. * The directions for 0.102F/D2 ratios selecting according to the materials and hardness range can be showing on the screen. * Equipped with the special Brinell indention measure system which can measure the Brinell indention accurately, quickly, reliably. It is a new measuring method by using CCD camera to capture the indention image, instead of reading diameter from optical microscope by operator then calculating the test value. * The KHB-3000A tester can connect any PC with USB port and runing the SPC software, then the special software supplying simplest operation. * Both single testing and batch testing mode are available * Tolerance setting, distinguishing and alarming * Statistics values such as Max, Min, Avg, R and S are available * Convert test result to other scales, such as HRC,HRB,HRA,HV,σb * All test results and indention images are saved automatically * Test report created in Microsoft EXCEL format, can be edit, copy, print as you will * Software update freely Technical data： Loads： 3000kgf (29400N), 1500Kgf (14700N), 1000Kgf (9800N), 750Kgf（7355N）, 500Kgf (4900N), 250Kgf (2452N), 187.5Kgf (1839N), 125Kgf (1226N), 100Kgf (980N), 62.5Kgf（612.9N) Load dwell duration: 2s～99s, can be set and stored Tungsten Carbide Ball indenter: 10mm Measuring range: 3.18HBW~658HBW Accuracy of indention measureing: ±0.5% Accuracy of Brinell Hardness Value: HD Range(HBW) Error (％) Rep.(％) ≤ 125 ± 2.5 ≤3.0 125＜HBW≤225 ± 2.0 ≤2.5 ＞ 225 ±1.5 ≤2.0 Max measurable height: 200 mm Max measurable depth: 140 mm Dimensions: 530mm×260mm×750mm Power supply: 220/110 V, 50/60 Hz, 4A Weight: 120kg Standard blocks: 125-350HBW10/3000, 125-350HBW10/1000 Standard configuration Host machine 1 Software disc 1 Standard block125-350HBW10/3000 1 USB Key 1 Standard block125-350HBW10/1000 1 USB Cable 1 Ф10mm Tungsten Carbide Ball indenter 1 Power supply wire 1 Mounting screws for indenter 1 Dust cover 1 Screwdriver for indenter mounting 1 Flat anvil, 80mmx185mm 1 Optional accessories: “V” shape anvil, 80mmx185mm Standard blocks of other value Ф5mm Tungsten Carbide Ball indenter Ф2.5mm Tungsten Carbide Ball indenter Ф10mm Tungsten Carbide Ball Ф5mm Tungsten Carbide Ball Ф2.5mm Tungsten Carbide Ball
