Advanced science.  Applied technology.



Using eddy currents and other electromagnetic methods, our engineers develop nondestructive solutions for inspecting aircraft structures, pipelines and coating thickness. We apply computer modeling, reliability studies, position sensing, and stress measurement. Our eddy current probe arrays inspect performance, speed, and coverage.
