Looks good, but you really need to get a probed thermometer so you can actually measure the hot side temperature (If you have one but it's not in the pictures then just let me know)

These are what I would recommend. They are cheap and accurate enough for what it is.



You can get them at Walmart for $12 Simply place the probe on the floor of the cage directly over the UTH, and place the unit on the cool side. This will allow you to measure the hot side temperature, the cool side/air temperature in the cage, as well as humidity all in one unit. Those dial thermometers & hygrometers really are junk and don't measure temperature in the right place anyway.
