1. Measuring range: 5-650HBW 2. Test force: 980.7, 1225.9, 1838.8, 2415.8, 7355.3, 9807, 29421N (100, 125, 187.5, 250, 750, 1000, 3000kgf) 3. The maximum allowable height of the sample: 280mm; 4. Distance from the center of the indenter to the machine wall: 150mm; 5. Dimensions: 700*268*980mm 6. Power supply: AC220V/50Hz 7. Weight: 210Kg.1. 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. The electric loading and unloading test force is adopted, closed-loop feedback is carried out by a pressure sensor with a precision of 5‰, and it is controlled by an ARM32-bit single-chip microcomputer and can automatically compensate for the loss of the test force during the test; 4. Solid structure, good rigidity, accurate, reliable, durable, and high test efficiency; 5. Overload, over-position, automatic protection, electronic afterburner, no weight; automatic test process, no human operation error; 6. Large LCD display screen, intelligent menu prompts, easy to operate, flexible and convenient operation functions with Chinese and English conversion; 7. Optional CCD image processing system to make imaging more intuitive and reduce human reading errors; 8. Accuracy conforms to GB/T231.2, ISO6506-2 and American ASTM E10 standards.Large flat workbench, small flat workbench, V-shaped workbench: 1 each; Steel ball indenter: Φ2.5, Φ5, Φ10 each 1; Standard Brinell hardness block: 2
