1. Measuring range: 5-650HBW 2. Test force: 612.9, 980.7, 1225.9, 1838.8, 2415.8, 4903.5, 7355.3, 9807, 14710.5, 29421N (62.5, 100, 125, 187.5, 250, 500, 750, 1000, 1500, 3000kgf); 3. The maximum allowable height of the sample: 230mm; 4. Distance from the center of the indenter to the machine wall: 130mm; 5. Hardness resolution: 0.1HBW; 6. Dimensions: 560*268*880mm; 7. Power supply: AC220V/50Hz; 8. Weight: 180Kg.Large flat workbench, small flat workbench, V-shaped workbench: 1 each; Steel ball indenter: Φ2.5, Φ5, Φ10 each 1; Standard Brinell hardness block: 21. The body part of the product is formed at one time by the casting process, and has undergone a long-term aging treatment. Compared with the paneling process, the long-term use of the deformation is extremely small, and it can effectively adapt to various harsh environments; 2. Car baking paint, high-grade paint quality, strong scratch resistance, and still bright as new after many years of use; 3. Solid structure, good rigidity, accurate, reliable, durable, and high test efficiency; 4. Overload, over-position, automatic protection, electronic afterburner, no weight; automatic test process, no human operation error; 5. Adopt electric loading and unloading test force, closed-loop feedback by pressure sensor with 5‰ precision, controlled by ARM32-bit single-chip microcomputer and can automatically compensate the test force; 6. Equipped with high-performance stepping motor for automatic loading and unloading, the noise generated during the test is smaller; 7. Automatically input the indentation diameter and directly display the hardness value, which can realize the conversion of any hardness scale and avoid the cumbersome look-up table; 8. Equipped with built-in micro-printer, and optional CCD camera image processing system and video measurement device; 9. Accuracy conforms to GB/T231.2, ISO6506-2 and American ASTM E10 standards.
