Is the eddy current magnetic field detector accurate?

Accurate. Eddy current magnetic field detector is a nondestructive testing instrument for detecting metal defects, and its working principle is to detect defects in metal materials through the principle of electromagnetic induction. For the internal defects of metal materials, eddy current magnetic field detector can detect and judge through signal changes. When used and operated correctly, the eddy current magnetic field detector can provide accurate detection results. Because the test results are influenced by many factors, such as the type, shape, size, depth, defect properties of metal materials and the quality of magnetic field detectors, it requires rich experience and professional skills to obtain accurate test results. In addition, before the eddy current magnetic field detector is used for detection, it is necessary to calibrate and correct the detector to ensure its accuracy and reliability.
