cool side temps...ambient or surface readings?

[nevohraalnavnoj]

Hi everyone, when we talk about cool side temps does it mean the ambient air temp of a thermometer placed on that side or surface temp of that side?

My BP's are in an acrylic terrarium with a UTH under the terrarium on the hot side (put on a rheostat) and a UTH on the back panel (also on the hot side, so it's a belly/back heat combo) which kicks out the majority of their heat (I will soon be hooking this up to a Helix thermostat). My cool side air temps are about about 79-80, but the temp gun says about a degree lower on the actual ground (I use paper towel). Should I up the UTH that's under the belly to get more heat coming up through the floor or is this okay?

Most people are measuring their cool side right at ground level, but don't generally have a probe in the cool side hide. Doesn't sound to me like you have anything to worry about. I wouldn't let the temps drop too much lower, but I don't think that the temps that you have now are anything that you really need to tweak.

If you ever get to worried about temps you can always get a temp gun. For me a temp gun makes a world of difference especially with racks. Good luck to you .

Hi Judd, thanks for the input. I do have a temp gun (I love that darn thing). If you go to your rack right now and it says 80 or 82, and you temp gun the plastic does it say the same thing or a bit lower??

Reviving an old thread!! Ok so here's a scenario. I finally got my oil filled heater on a ranco set at 82. What a dream!!!

And I've got temp probes on the hot and cool side as well as a helix on both the hot and cold side.

But like my cold side helix is set at 85. I get 82.5 to 83 degrees on the floor. But the ambient temps are almost a degree higher.

I was wanting to pull that helix and put it on the bloods tub. Would ambient temps of around 83 be ok if the floor temp is a tad lower?

And just have the oil heater keep the cool side temps high enough?

That way I can get the johnson control that's on the bloods tub off and use it as a back up. And also give him some more stable warm side temps.

Hope this all makes sense. Thanks for anybodys help!!

I could be wrong but i dont tink it makes a difference... The reason higher ambient temps is a must is becuase of the potential RI... I dont own bloods nor do I know their requirements and hopefully someone will correct me if im wrong... but Id say anything above 80 degrees you should be OK. You just need to worry when your cool side/ambient temps are dropping anything below 76

Oh the bloods temps are fine. I'd just like to put the balls cold side helix on the bloods tub to give him more stable temps.

I was just asking if on the balls tub if the ambients are 82-84. With the floor being about that. Could its flexwatt be pulled. And just rely on the heater in the room.

Thing is is that the floor temp is a degree cooler than the ambients. Would that be a problem? I think that's what its all boiling down to.

I personally dont see a problem... My balls cool sides are between 78-80 and I have no problems and all of them thermoregualte normally... If your looking at anything above 80 I dont see an issue with making the switch... Either way its the cool side so I dont think it makes a difference because well... its supposed to be cool

Allright well I did it. I pulled the uth off the cool side. My ambient temps remained the same. Maybe a half a degree lower. But in the 82 to 83 degree range.

Now I've got 2 acurites right next to eah other. 1 for the cool side. And 1 right next to it with its probe on the warm side.

But the probe on the cool side floor says 80 to 82.

Still okay? I had to bump my ranco on the oil heater to 83 from 82. To keep the cool side a bit higher.

Any tips or thoughts are appreciated. Just don't wanna get any ri's.
