Problems with Al Xeu 10/20/2005

I am trying to make some temperature measuraments with a infrared camera in a Al sample. The idea is to drill some holes and measure the surface temperature of the sample.

The problem is the low emissivity of the Al. I donĀ“t know if the measurements will be enough reliable...

Will it be O.K to paint the surface of the sample with a high emissivity paint (black...)??

Has anybody done similar things???

Thank you and escuse my english.

Painting the surface or placing a piece of black vinyl electrical tape (e~0.95) on the surface are easy ways to improve the emissivity.
