摘要

PROBLEM TO BE SOLVED: To accurately estimate the amount of wall thinning of a metal member made of various materials and in which gas flows on the surface. An estimation method is provided. SOLUTION: The device for estimating the amount of wall thinning of a metal member through which gas flows on the surface, and the device for estimating the amount of wall thinning of the metal member includes a probe arranged flush with the surface of the metal member. The probe has an insulating base portion made of an insulator, an arrangement test body provided on the insulating base portion, a reference test body provided on the insulating base portion, and an insulating base portion on the surface of the metal member. The reference test piece and the placement test piece are electrically connected in series, and the surface of the insulation base portion, the surface of the placement test piece, and the reference test piece are provided. The surface is provided so as to be flush with the surface of the fixing member. [Selection diagram] Fig. 1
