I would ditch those gadges, they can be really inaccurate. I got a temp and humidity probe from Walmart for like ten bucks that works great. As long as no scales were pulled off and there is no wound he should be fine. But in the future, if any animals (or human for that) gets something like that stuck on them you can use baby or veggie oil to remove it easily. I've done that to get geckos off sticky mouse traps that a pet store used.
