Any one have a recommendation on a good dial thermometer that can be mounted directly on a brewpot and not get damaged by overheating during normal use? Preferably one with a 1/2" NPT male connector. I've been using a readily available dial thermometer (B1 and B2) on my Keggle for years. (Vendor names omitted). Recently I tested them, along with every thermometer in my household to see which of them are accurate and here are my results. Turns out the B1 and B2 thermometers are way off. I am pretty sure I damaged them long ago by exceeding the case temperature maximum. I expect the brewpot metal exterior, with a propane burner under it, gets a lot hotter than 212F. I'm now using the T1 wire probe thermometer for mash temperature, but I still would like a dial thermometer installed on my Keggle.....which is the recommendation I am looking for. JEGS makes a liquid filled engine coolant thermometer intended for installation on engine intake manifolds, and that means it can probably hold up to at least 212 F. But I am not sure it is food grade so I don't plan to use it. I'm thinking the ultimate answer here is to NOT install a dial thermometer on the brewpot. They are not designed for that environment.
