TheThe Accurite units are OK for stuff up to about 50% or so, as I have some units going more than 2 years, but it seems anything much above that humidity send them to an early grave. Same with the reptile branded digitals, I have a whole pile of those that are basically useless now. I like the look of that one you posted, just might order that when I get back from vacation. Thy even look like they would stand up to being misted, since they are supposed to be for outdoor use. And that would be enough to do all my gtp cages if I ordered the extra sensors.
Edit: Oh geez, they even have a wireless temp sensor for your pool, or in my case the turtle pond.
