To all,
I'm surprised that no one hasn't mentioned this yet. In the past for this application, the securement that I was introduced to was fiberglass tape and that white thermal grease. The tape exhibited high thermal stability and was used to secure the thermocouples, but left adhesive residue when removed after a temperature test. The thermocouple was inserted into the grease which offered excellent thermal conduction from the measurement point to the thermocouple. The downside to this grease, as anyone who's used this grease would say, is that the grease is "messy to the extreme" and it generally could not be completely removed from any surface that it came in contact with. And, it always found a way to get onto unintended surfaces including clothing. But, as a plus, the thermal grease would stay put physically over a very wide temperature range. I'm sure that someone has fond memories of that stuff.

A former agency engineer I worked with also used this waterglass adhesive for thermocouples. It worked great and was usually easy to remove thermocouples without damaging.
