Variable frequency magnetic detector combines alternating current, direct current, rectified current, and impulse current to test flaws in depth and in high sensitivity. It broke through the limits that magnetic particle testing tools can only detect surface defects of metals, and solves the problem that it is difficult to test thin steel plate using ultrasonic flaw detection. It can work for 8 hours without external power, and has the functions of camera, video and white and UV illumination.
