So I have been using the ebay temp controller for a year or so now. I have been taping the probe to the side of my buckets (now carboy) and then putting a folded face cloth over that and using two bungee cords to hold it on. I thought that was working great...until just now. I took my carboy out to dry hop and noticed the temp rose 1°C (which was about 1.8°F). 2°F isn't all that much but if it rose that much after being out for less than 5 minutes, I'm thinking the probe isn't insulated enough. I highly doubt the 5.5 gallons of beer rose 2°F within the 5 minutes.
What does everyone use to insulate their probe? Have you noticed that kind of temp change when taking your primary out of the fridge/chamber?
