Then use a little tape to clamp the sensor to the tubing so the sensor doesn't move. Covering it with a piece of tubing insulation foam is a good idea.

I actually tried thermal heat sink compound. The white pasty stuff. I still had readings that seemed to vary.
I wonder if the leads coming off my thermocouples are the issue. The actual thermocouple is a tiny dot with two very fine wires coming from it. Just the thermocouple and a bit of the leads are exposed and the rest of the end of the cable is covered by a piece of heat shrink tubing.
I wonder if the two fine wires aren't insulated well and I'm having issues because of it. I'll try a few things and see what I can figure out.
