I know they are known for being quite inaccurate, but I have two gauges that read both humidity and temp from different producers (not sure the brand names, they are probably from zoo-med or other things found in the pet store, I haven't been able to get an electric one yet) though I'm fairly certain they are mostly accurate. Cool side reads between 75 and 80 degrees F and hot between 85 and 90. and currently the cool side has around 70% humidity while the warm has around 65%. I have both a heat lamp and belly heat, though I feel like the heat lamp might be baking her skin on even though she is in a hide (its one of the lower watts)? She usually chills all day on her UTH and doesn't normally switch sides to regulate temp
