The system hardware circuit and software design was used the analog impact galvanometer, microcomputer technology and electronic technology. The design can change the analogy signal into digital signal,and display into digital tube. The test results show that the system can successfully achieve the measurement of the static magnetic parameters. Compared with the analogue impact galvanometer,its accuracy and resolution is up to 1% and 0.0001.The system not only meet the quality testing of magnetic materials,but also can be applied to education.
