SY-8218/SY-8219 high-frequency B-H testerIntroduction:

SY-8218/SY-8219 high-frequency B-H testerA specialized instrument used to test the magnetic properties of soft magnetic materials such as silicon steel sheets and ferrites, evaluating material properties by drawing B-H curves (magnetic flux density magnetic field strength relationship curves). Its measurement parameters include maximum magnetic flux density, coercivity, power loss, and magnetic permeability, supporting both DC and AC measurement modes. The built-in thermal printer can output chart data such as AC return lines and magnetization curves. The application areas cover the research and quality inspection of soft magnetic materials such as power equipment and electronic components.

Main measurement items‌：
