Regular price $40, I was just there and found it was down to
$26.99. A thermocouple is a tiny junction of two metals that makes
part of a highly accurate thermometer that can stand -very- high
temperatures.

This one goes up to 2000F or 1300C.

Harbor Freight Tools, Cen-Tech 92242. Reads in C, F, or K.

Since it is a contact thermometer, it does not matter what color
the surface is, unlike non-contact pyrometers where the surface
must either be a dark black/grey, or you have to stick a piece of
black high temp tape on it to test it.

It has some funky cheapo connections on the meter, I figure I can
replace those easily enough with something standard. Even a 1/8"
jack, as long as it's close enough to the cold junction
compensation.

Naturally I'll take it apart, I'll take a few pix of it.

FYI, they also have a 6" digital composite (ie, fibersomething
filled plastic) on sale for $8, inch or mm.
