sanke fermenter question

[elCreed]

So out of curiosity, how do you measure the fermentation temp in a sanke fermenter? Do you just assume it is the same temp the fridge is set at or is a thermowel/thermometer setup needed? Would a sticker thermometer like I use on my carboy work?

You could tape a temp probe to the side of the fermenter and tape some insulation over it... should be pretty close to the internal temp.
