Measuring Coating Thickness at Hig Temps

Im currently looking for an instrument to read thickness of a non-ferrous coating on a ferrous substrate, with a surface temp of 500 F. Magnetic gauges only go to 400F and are affected by high temp. Can anyone suggest a product?

Measuring Coating Thickness at High Temps The Lixi Profiler can measure at high temperature the thickness of a coating on ferrous material if the X-Ray absorption of the coating is at least 2% of the ferrous material

What is the coating material and what is the thickness range? It may be possible to do this ultrasonically, using a high temperature delay line transducer, but I need more information about exactly what you're measuring to comment further.
