I am going to do some ghetto fermentation temperature control this summer by putting my glass carboy into a cooler with ice water in it. I'd like to be able to read accurate temperatures from inside the carboy, so I though about just leaving my handy type-K thermocouple inside the carboy, and running the wire out beside the stopper. It's a really flat wire so I should be able to seal around it with tape really easily. That way I can attach my multimeter to it at any time and get a really accurate read.
My question is, will the acidic wort interact with the thermocouple? It's not shielded in any kind of copper or stainless steel sleeve, so the constituent metals (nickel, chromium, manganese, aluminum) will be exposed to the wort. Anyone know if this is a bad idea?
Here's a link to the probe in question:
