DO NOT GET THE RANCO PROBE WET! Ask me how I know. I use a ranco dual stage with a thermowell that goes inside the fermenter. That also handles the short cycling problem. In my keezer, the probe is in a thermowell - in a 20oz plastic bottle filled with water.
Yes DO NOT SUBMERGE THE PROBE IN ANY LIQUID. I did a study with tapping my Johnson A-419 to the side of a 6.5 gallon glass carboy and in a thermowell on the same carboy with the same yeast at the same temp. There is a 1 degree difference between the 2. Tapped version is 1 degree cooler than thermowell. So i offset my Johnson to compensate. A Pic for ya
