I am using a small commercial cooler as a fermentation chamber. It is equipped with a temperature controller with the probe firmly pressed against the glass carboy under a 3/4" layer of closed-cell pipe wrap foam. I have calibrated the probe.
I have never attempted to compare this temperature monitoring method against an actual temperature reading of the liquid within the carboy due to the lack of a thermowell. I have always assumed that the offset would be negligible, in the range of a tenth of a degree or so.
Has anyone made a comparison between actual liquid temperature and external probe temperature readings? Am I way off-base in my assumption?
