I use one of those 10 gallon orange Rubbermaid coolers for my mash tun. Up til now, I've been using a probe thermometer to measure the temperature, but that's getting to be kind of a pain.
I'd like to install a thermometer into through the side of the cooler, like you see in most boil kettles. Has anyone tried this? If so, did you need anything special in terms of the thermometer? Was the install pretty simple?
Morebeer.com sells a 6" thermometer for this purpose (http://bit.ly/bgJd7A
), but warns that "Special tools and training are required to install this unit. This must be done here at the shop." Sheesh, how hard can it be?
