Abstract
To provide a surface property inspection device and method capable of inspecting the surface treatment state of treated material subjected to surface treatments. A surface property inspection deviceincludes an AC power supply, an AC bridge circuit, and an evaluation apparatus, and the AC bridge circuitis formed by a variable resistorwith a distribution ratio of γ, a reference detector, and an inspection detector. The inspection detectorincludes a coilwound so as to oppose the surface property inspection area of the test object M; an eddy current is excited in the test object M by supplying AC power to the coil. A reference test object S with the same structure as the test object M is placed in the reference detectorto cancel inspection environment effects.
