Sorry, I don't mean to hijack but a light went off here.....
Hey, I just bought 2 of those things and never knew that! Ok, so did I set up mine correctly?
I placed the probe for my accurite on the glass over the UTH, and then put the subtrate over that. The UTH is connected to a ReptiTemp 500. So along with the probe for the RT 500, I have a probe for the accurite...is that right?
The the inside reading should read the same as my cool side thermometer?
