Since getting serious with fermentation temps, and buying a fridge to dial into a specific temperature and thus control my fermentation temp with OCD-like accuracy, I've wondered how close to the wort my STC-1000's temperature sensor needs to be in order to get the most accurate reading without going to unnecessary lengths.
Initially I had it simply taped to the interior side of my fridge.
Later I realised this wasn't measuring the temp of the fermenter itself, nor the wort, so I attached it to the exterior of my fermenter with some tissue laid over it in order to insulate and measure only the fermenter temp, not the fridge's ambient air temp.
Tonight, while pondering fermentation temps for my first rendition of the Adequate Saison, I wondered if I'd get a different reading by submerging the probe in the wort itself. off I went to sanitise and dunk said probe, and its readout is 0.2deg higher than the reading from the exterior placement w/ insulation.
The purpose of this topic is twofold;
a) to inform all the less experienced brewers here that an STC-1000 costs bugger all (eBay it) and is awesome, and
b ) to discuss whether there is any merit to placing the temp probe in the wort as opposed to attaching to the exterior of the fermenter.
What are your experiences?
EDIT: despite living in the MSN Messenger era, typing b ) without the space in between still catches me out with the good ol' sunnies smiley. b)
