If you want to be able to un-stick it and reuse it on another enclosure, what you can do is remove the paper backing and then use aluminum foil tape (shiny side out) to cover the sticky side so it's not sticky anymore, and then with some more aluminum tape you can tape it onto the enclosure. That way you can untape it whenever you want.

thats really good thinking! I dont want it to be directly on the glass because i use 3 sheets of paper towel as substrate so i dont want him to burn. My thermometer probe is on the side of the glass above the UTH.
