Thermal camera that can see the heat of glossy and matte surface?

[daslolo]

I am using a seek compact pro which has glossy setting, it only multiplies temperature though so I cannot evaluate the heat movement of matte and glossy components in the same picture.
Is there a system that can?

I believe some of the FLIR ones allow you to add an "emisivity map" so you can use it across multiple surfaces, but you have to somehow generate that map for your specific object which is really painful.

The usual simple approach is to paint it, matte black spray, even in a less than complete coat, does great.  You could also try masking tape or similar, all provided that the temperatures involved aren't too high to allow it.

Just modify the surface:

Thanks folks,
I'd like to apply something temporary on these dedicate PGS ribbons, does anyone knows of a paint that crumples after some time?

Masking tape or plastic tape are my normal go-to materials because they work resonable well and are cheap.

There are India inks that aren't very waterproof. Maybe airbrush with one of those, then clean in ultrasonic cleaner with a bit of ammonia afterwards. Or maybe make your own- you need a pigment and a lousy binder.  I do a lot of IR temp measurement and IMHO paint is the easiest solution.

I painted the PGS with china ink, it shows heat much better but also insulates the PGS so heat dissipates less.
Apparently you can't see heat without changing the conditions.
