摘要：

The paper describes a technique and an instrument for simultaneous absolute thickness measurements of components in structures composed of a nonmagnetic coating and a ferromagnetic base. The technique is based on measurements of the normal magnetic induction component of the secondary field at two points and comparison of these measurements with similar parameters of reference samples.
