Hello all. I recently upgraded from those half-dollar size stick on thermometers to an indoor/outdoor digital. WIth the old ones I just stuck 'em on about halfway between the floor of the cage and the light source and didn't give it a second thought. Last night this is also where I stuck the digi. After about 20 minutes it was reading 90, good for my burm's hotspot, but when I woke up it had fallen down onto the bottom of the cage directly beneath the light and was reading 110! I never thought there would be such a drastic difference from such close points. My question is, where do you all recommend placement for the best readings?

The temps may be correct, how are you controling the heat in the cage and what type of heater is it?

I have a UTH on the cool side which keeps the substrate at about 80 degrees, and a clip lamp with a 60 watt bulb on the hot side. He's in a Rubbermaid that is approximatelyu the size of a 20 gallon long.

I believe you are sticking the thermometer or it's probe on the glass? This is only my opinion: On the glass you are not getting a temperature that means much. It's going to be between the cage temp and the room temp somewhere. Glass is inherently more a better conductor than an insulator. This means if the room if cool, will cool that glass a lot. Well, the cool room will have a great effect thru the glass to the thermometer. Changing the reading. Unless the thermometer has some space away from the glass I think its a bad place. Most reptiles will not be in that place anyway, unless wall geckos or tree frogs. I use to use some indoor outdoor thermometers. I use to place the probe in the hot area, either on a rock, or even just on the substrate. Even this can be miss reading because the probe can be black. I painted 1 white that worked well. I also placed something over it to block the probe from giving a false reading from the light.
