I've been meaning to do this for a while now but I burned my temperature probe cable and I had to wait for a new one to come in.
I have a johnson analog temperature controller seen at the top of the page here NORTHERN BREWER: Fermentation Temperature Control
I wanted to know just what temperature my fridge was compared to the temperature setting. In the experiment I had the controller set to 35*F, and the bulb of the controller as well as the temperature probe resting on a cardboard six-pack carrier to get a good air temp. As you can see it was a pretty even bounce between just under 38 and 43 *F. I figure that puts the beer at 40*F or just above.
