Problem with Thermometer probes in high humidity?

[Slannesh]

Hey all,

Just wondering if anyone else has had similar issues as i've had.

Recently I set up a cooler style incubator with water heated by a submersible fishtank heater. The heater is a good one (Tronic 200W) which is the same model I use on my 33gal fishtank and it works flawlessly. But recently i've noticed the temps that my digital termometer were showing were WAY out of whack.

It's the little oval white type with grey buttons that everyone seems to use Springfield Precise temp is the brandname. The probe comes covered in a little plastic nub with a bit of double sided foam holding it in. It was full of water so I removed the plastic bit leaving just the probe and about 3mm of exposed legs. I thought that would help and it seemed to for a while but this morning I checked the temps and it said it was at 110 degrees F. So, freaking out I grabbed my temp gun and checked the temps in each of the egg containers. 80-81 degrees just like they're supposed to be. So what i'm wondering is would the exposed legs of the probe be giving me whacked out readings because of the high humidity? The same thermometer seems to work perfectly fine in dry environments of all temps (I confirmed by using multiple thermometers and my temp gun to be sure)

If that's the case does anyone know a brand name of digtal thermometer that I could buy that keeps track of min/max temps that can handle the humidity in my incubator that I can get in Alberta?

Also, has anyone else had similar issues with that or any other brand of digi thermometer before? I'm now finding myself not entirely trusting about half of my thermometers all of a sudden.

Thanks!
