I place the probe in the center of the tank right now because I don't have two to messure both sides and I get a reading of about 85degrees.
Oh, I know that you're trying, if I implied otherwise, my apologies.

I'm not sure if you were aware that you can buy one unit for $12 at Walmart in their hardware section. It measures indoor and outdoor temps (indoor = cool, outdoor = warm) AND humidity. The brand is AcuRite.

You can even buy it online here:

In the picture, the top reading is time, and you can switch that to temp, so you'd set the unit inside your enclosure (I actually velcro mine to the side) at ground level on the cool side of the enclosure and then run the probe to the inside of warm side hide to measure warm side temps.

Hope that helps!
