As for the thermostat. The urine would cause a liquid state over the thermostat seeing the probes are sealed this is not a proble. However it will create a denser mass creating a larger heat sink making it more accurite.
Having the probe under gives you an inaccurite reading it is more accurite having it where the snake would lay.

The cheapest temp gun I can get is $25, I can get a accu-rite thermometer with probe at wal mart for $10.

The probe doesnt matter if its sealed, if you poor liquid on it, then temps are lowered plain and simple. Liquid cools. This would cause a spike in temerature.

However the OP has decided to try a rheostat so this wont be a problem...
