Wv-10a /50A Vickers hardness tester Adopts new aluminum alloy die casting process, the shell is firm and stable, novel and beautiful. The closed-loop loading control system is adopted, and the vertical loading test force is directly driven by the motor, so the test force is more accurate and stable. The turret is faster and the test efficiency is high. Using special material lifting shaft, ball screw structure, more stable lifting. The instrument adopts a new 8 inch large color touch screen, intuitive and clear display, Angle adjustment, easy to operate. Equipped with digital display micrometer eyepiece, no need to look up the table, nor input the indentation diagonal, on the touch screen intuitive display of the test force, indentation length, retention time, conversion ruler, time, etc., as long as the operation of the indentation measurement press the eyepiece button, can automatically calculate the hardness value and display on the screen. Real-time storage of hardness test results, data classification, optional deletion and print output, automatic calculation of maximum, minimum and average; And equipped with RS232 interface for users to connect computer output. LCD video measuring device and CCD image automatic measuring system are optional.
