I cleaned to tank and put the thermometer probe on the glass above the UTH. I put a sheet of newspaper over the probe and aspen (1 to 2 inches) on the newspaper. I have the hide on top of the UTH.

The probe reads 99 degrees at the hottest spot (gets lower as you move away from that spot). I took a reading on the top of the aspen with an infrared temp gun and it read mid 70's.

Does the temp gun work on aspen?
Does it take a while for the aspen to heat up?
Will the heat build up inside the hide?

I'm going to put another probe in the hide, on top of the aspen, when I get home tonight. I'm curious to see what that reads before I open the hide and use the gun again.

Thanks.
