That's a great article. Basically, placing a small piece of black vinyl electrical tape on the amp's surface (Scotch Brand 88 is recommended; kapton tape also works) will raise the emissivity from near 0 to nearly 1 (0.96 is that tape's rating over both short and longth IR wavelengths). Article shows a useful example: an aluminum can filled with hot water, with a small piece of electrical tape affixed to the outside. The outside of the can reads 74F when the thermal camera is pointed at the aluminum, while it reads 163F when pointed at the tape. Simple concept, very useful. Thanks!
Use Low-Cost Materials to Increase Target Emissivity
In many industrial R&D applications, there are many low-emissivity targets, especially for electrical applications. To get good measurements, we need to increase the emissivity of these problematic targets. A thermal imaging camera records the intensity of radiation in the infrared part of the...www.flir.com
