Hi,

My rack is a 4 high 41 qrt herpenclosure rack. My temps are driving me nuts as I can't get them to where I want them. Not even close.

I taped the herpstat probe directly to the 3inch heat tape. I put 3 different digital thermometers in the tub for testing. Here were my results:

- ambient room temp was 72
- herpstat thermostat was set to 100
- digi thermometer taped directly to heat tape 94
- hot side 80
- cool side 76

What the heck is going on? Is there really a 14 degree difference from the temp probe taped on the heat tape and the temp probe taped to the bottom of the tub on the hot side. What is that 1inch of space??

How high can i crank the thermostat up to make up for this? How hot can i let the heat tape get to? I seems I would have to crank my thermostat up another 12 degrees (112) to get it to the 92 on the hot side.

Any help would be appreciated.
