Thermometer above paper towel or below?

[TranceZ]

Hey everyone, I did a little experiment today and while I have all my thermometers under my paper towels in my tubs, I decided to place another thermometer on top of the paper towel to see what temp difference it would be

At first I was getting temps of 85 above PT and 93 Below PT. So basically my leos were getting temps of 85 I guess. So I turn up my dimmer switch.

I drew a picture of what I'm talking about.

1. Above thermometer
2. Tub
3. Paper towel
4. Heat Cable
5. Below thermometer

So my question is should I just go by the temp above or on top of the paper towel and ignore the below temp?

Above the paper towel.

you always want the desired temps where they are lying on and that the paper towel

Crazy how there's a 9 degree difference between the paper towel and the heat cable

Some materials are better insulators such as ceramic & wood products, some are better conductors, like stone. I don't find it too incredibly odd.
