The problem I'm having is that it reads about 4-5 degrees lower on the bottom of the uth that it does inside directly on the glass. Do I just test the temp of the repticarpet over the uth inside the tank with my IR, gun and adjust the thermostat so read 90-92 on to of the repticarpet?
Try and see if you can get the probe in between the glass and the UTH. You may have to peel back a bit of the UTH to do this.
That will be a much more accurate reading. Under the UTH may not be where (I think with Zoomed) the heat emitted.
