Temp Control on Keg as Primary

[Jboggeye]

I have a chest freezer with a ranco controller, and just moved to fermenting in Kegs.

What's the best way to control ferm temps when using kegs as primary?

thermowell? Probe taped to side of keg?

Short answer, either way is fine.

I tape the probe to the side of the keg and insulate it on the outside with a sponge.

Great technique. Reducing the external heat load on the sensor and getting the sensor as (thermally) close to the UUT (unit under test) is the best anyone can do.

I use a bungie cord with a foam backing. From what i can tell, it's pretty accurate.

thanks all. it's what I do with plastic buckets, carboys...

Upon further research, it sounds like the stainless steel of the Keg might actually be even more accurate than either the glass or the plastic.
