GE Inspection Technologies has multi echo probes for through paint measurements... Also, there are advanced phased array dual element linear phased array probes for corrosion mapping. check out this link

Hi Ramesh, There are many advanced corrosion mapping systems on the market and I suggest you take a close look at as many as possible on the internet to get an idea of what is available, what these systems offer and how they might fit into your work requirements. May I suggest you include the AGR.com - Ultrasonic Technologies section in your research and contact me directly if you have any specific questions. Good luck.

A rapid corrosion scanning technique ( with mapping) that also allows you to go through paint/linnings up to 10mm thick is called SLOFEC (Saturated Low Frequency Eddy Currents) Please look at the Innospection website www.innospection.com for further information and data.
