Enclosure Set-Up Advice

Okay, so I've done some looking around and I think I found some thermometers and hygrometers that should work.

^ I plan to put that one on the cooler side so it can measure ambient temp and humidity.

^ I plan to put the probe on this one on the glass above the UTH and set the base pretty close to it.

^ I'm also getting this dimmer for my heating pad.

Do you guys think this setup will work?

My only suggestion would be to look for a different probed thermometer. That one that you linked still has a receiver that isn't exactly tiny and probably won't measure surface temps all that well.

The pet store should have a single probed thermometer that isn't too expensive.

Okay, I'll check my local pet store and see if I can find one like that.

I'll try to post updated pictures tomorrow.

Okay, I'm finally back. First, thanks so much to everyone who helped me configure her set up properly.
I got the thermometers and humidity gauge like I posted. The hot side (right above her UTH) stays right around 90 because of the dimmer, and the ambient temperature is usually anywhere from 80-83 (and I switched to only one light in the center of her enclosure). So her temps look great, but I'm having serious problems with her humidity.
The natural humidity in the room she is in is around 16-18% (winter in Oklahoma, sigh) and I'm struggling hard to stay on top of it. I'm using a humidifier, but that only raises the humidity to 22-24%. Obviously, I'm misting her to at least 50% whenever I can, but when I'm asleep and when I'm at work, there's nothing I can do, and she drops back down to the 20% range again. I've tried putting a damp towel over the enclosure (over her water bowl) because I've heard it can help, but it's really not making a difference. Also, her bedding is cyprus mulch, which I've also heard helps retain moisture, but that's what I've always used for her bedding, so I can't tell if it's making a difference or not.
Does anyone have any ideas to help raise the humidity by 30%? Thanks!
