i have a infrared thermometer and a digital thermometer/humidity sensor. as i said, some things have changed since that picture was taken, the lid was covered to prevent humidity loss, which is now hovering at about 50-55%. the acu-rite was also added after the picture was taken. as far as the UTH and thermostat are concerned, for right now, i'm not sure i need them. warm side is sitting at about 88-90*, cool side at about 84* and airtemp at 85ish.
