Abstract
The purpose of this paper is to experimentally demonstrate advantages of the new matrix type sensors useful for testing of planar specimens made of Inconel 600. A computer controlled ECT system used for multi-frequency testing is also described. The extended experiments with the sensors were performed and their results are presented. Results of the comparison of the sensors are given
