This topic has been on my mind lately because I'm looking for something easily mountable. I have three of the ones listed above. I tested all three last night and the two Accurites had similar numbers (2-3% humidity difference and 0-2 degree temp difference. Note: All three were placed on the cool side of the enclosure.

However the TH-100, had a 6-10% higher humidity difference and a 1-2 degree higher temp difference.
