Water messed up my Love probe. Had to build a new one.
Not hard, by the way. used the same wire, soldered it to a new thermistor, dropped it into a brass tube, epoxied both ends... now waterproof.
Thermistor - Digi-Key, $0.77 ea. Shipping $2 Look for thermistor that is 1000 ohms at 25C
brass tube - hobby shop. (mine sits in the water bath of the fermenter, not in my beer).
EDIT - now 89 cents. Look for P/N 568-1003-ND
