The probe to the thermostat controlling it is inside the tank, and the cable is imbedded in silicone, leaving the actual probe exposed. It's not going anywhere. Running right alongside the probe for the thermostat is a probe for a digital thermometer, imbedded the same way. If the readings don't match, I start troubleshooting.

There's a SECOND thermostat connected to the heat lamps to regulate ambient air temps. There are also digital combo meters at each end of the tank. PLUS, I have an IR thermometer to spot check. It would be VERY difficult for my temps to get out of control.

Yes now it makes sense, I was a little confused about your setup at first. To the OP you can mount the tstat probe in or out, if you do it in you need it secured like the above description. For ease of use, mounting it on the outside works just a well.
