Thickness measurement is essential to precise condition assessment of steel structures. In this research, the pulsed eddy current (PEC) thickness measurement method is studied, which can measure thickness without the surface treatment. The applicable limit of PEC is examined by measuring the thickness of specimens with various types of thickness loss and performing a finite element method for thickness-reduced steel plates of different types. As a result, it is found that to measure the reduced thickness of a small pitting is difficult, but to measure the average thickness is possible when thickness reduction is spread in a wider area. In addition, a measuring range of PEC and the effect of specimen's shape on measured thickness values are identified.
