MHB-3000 Digital Brinell hardness tester

MHB-3000 Digital Brinell hardness tester

The machine adopts the current  new full-automatic closed-loop sensor control technology. The stepless servo motor directly drives the ball screw to apply force, and the force value sensor feedback the force application process and size to micro classification, so as to eliminate the over loading or less loading fluctuation caused by the hydraulic or motor deceleration error or the spindle knife edge friction with the increase of the use time of the traditional weight lever amplification loading system. The system has overload and over position automatic protection function, 10 level test force selection and 14 level test scale; Solid structure, good rigidity, precision, reliability, durability and high testing efficiency; The test process is automated, and no one is responsible for the operation error; Large LCD screen, intelligent menu prompt, easy to operate; High precision reading microscope measuring system; Optional automatic indentation measurement system;
