At any rate, what do you have your temp controller set at? Mine is set at +/- 1 deg. And I tape the sensor to the carboy.
It's a Love TSS2 controller on a chest freezer with the temperature probe on the side of the carboy with insulation over it. More details on on Posts #80, #83 & #84 on this thread:http://www.homebrewtalk.com/f51/another-tss2-controller-box-build-195713/index9.html
The data logger is an Extech EA15 with the (2) type-K thermocouples that came with it. I do work with industrial heat transfer equipment and my company has these small data loggers and 60-input Agilent ones & hundreds of high accuracy thermocouples. This is my 2nd fermentation with the Love TSS2 controller and seeing the data really helps know what to expect. I was using a Johnson A419 before this as discussed in the thread.
My cooling setpoint is 63F and 0.5F differential. The heater would come on if the fermenter dropped to 61.5F and would increase the temperature to 62F.
I'm hoping for a really clean fermenation and a beer that is similar to Dead Guy.
