Help with thermostat

[lisafoster2510]

I have my hydro farm set at 92 but my temp gun is reading my Uth at 82 can I bump up the temp on my hydro farm. A herpastat is on my list just not today

Are you gunning the actual UTH, the glass above it, or the substrate over it? In theory you would up the stat, but that's a pretty dramatic difference.

I am moving the substrate and using my temp gun there are areas that are reading 75. I am putting my hand on the Uth it barely feels warm. Both the Uth and thermostat are new I did put a digital thermometer there and I am getting the same. It is about 10 degrees off.

[Annarose15]

How long has it been warming up? Is the UTH in direct contact with the glass/plastic of the cage?

Just trying to narrow down the possibilities.

It has been on all night. It is a zoomed so it is adhered to the bottom of the tank. The probe for the thermostat is between the underneath of the tank and the Uth. Maybe I should take the snake out and run the Uth without the thermostat see how hot it get see if the issue is the Uth or the thermostat.

I think this would be a good test to run. I've had to set mine 5 degrees high before, but never ten.

I'm pretty sure ZooMed UTH claim they only get about 10* warmer than the ambient air temps.

I had a few laying around and was going to use one for a quick fix a couple of weeks ago. It hit 120* in about 10mins.
I threw them all out.

Lets see if we can narrow the range of possibilities down some. Can you place the probe of your thermometer beside the probe of the hydrofarm. If you want you could use the IR gun to check that spot just not the probe itself they cannot measure metals especially shiny metal accurately. (shiny plastics also can be problematic)

The second question is what is the room temp? This will have huge impact upon your surface temps.

The temps are cold here today it is 39 degrees outside my house temp is 68. Maybe I should bump up the thermostat 5 degrees ? I'm having a wicked hard time getting my temps up in the enclosure my house is 200 years old and the temps really fluctuate. Maybe that could be what's going on.
I can't get the temp gun next to the Uth the zoo med is stuck to the bottom of the enclosure. Plus I have several stacked and I am not strong enough to move them I need to wait until my husband gets home. When I put my hand on the Uth where my snake is I can feel it is not warm enough. I have an infrared bulb but I was told by my breeder not to use it I am struggling with my humidity my house is very dry. I turned it on for the last hour now my ambient temps are much warmer but the Uth still is not.
I just took it again after an hour with the bulb on it reads 86 so maybe the bulb has to stay on because it is so cold outside . so now the thermostat is off maybe 6 degrees.

What kind of enclosure is it? A tank from the sound of it.

It is highly likely that 68ºF is having an negative effect on the system. It is hard to maintain correct temps under this conditions (remember hot/warm spots are one 1/3 of the temps cool side temps at the surface and the air temp matter as well.) 90ºF/80ºF and high 70s to low 80s for air temps.

Hydrofarms preform poorly in cool rooms they just don't handle the rapid changes in cool rooms well. They also do not have good accuracy, the spec's are rated to 2ºC up or down that is about 4ºF over or under correct.

My guess and it is just a best guess is that some of the issue is accuracy of the hydrofarms (why I suggested getting the thermometer probe as close as possible to the hydrofarm to check this) some of the is from the rooms temps as well and some is possibly how much substrate you have.

I don't think they will be an ahha moment where one thing will solve all the issues I think it more likely a bunch of small things are acting together.
