There is an industrial insulating company about three miles from me. I don't have high hopes that they will have what I need, but, if they do, I might be able to get some free scraps. Then I'll try the HVAC place about 5 blocks away. If neither of them can help, the only other place I can think of is auto parts stores and see if they have some kind of thin, foiled exhaust blanket or header wrap with foil.

My panel meter will take J, K, & T; any of which should do the job (plus R and S, but those aren't a good choice). For what I'm doing, twisting some extension wire together would probably do the job; relative readings will be more important than absolute accuracy. I have a J or K that I use to measure temp in the garage, but it is in an industrial sheath and has a lot of lag. Will try to find a real t/c, but could strip the sheath if need be.
