Thanks actually last time I did a check my ambient was 45 and I had the probe in a jar of water setpoint 38 for a keg of course. And the jar water was like 36 Why such a big difference? Again thanks for the input on this. I have a starting point now just need to decide where to put the probe. Water jar, in the air or foam method. Do u think for fermentation it is OK to assume all is well using the ambient temp method? Thanks again not trying to over complicate just want to get it right with investment I have made.

Most probes state they shouldn't be submersed. I know people do it, but it may not be a good long-term solution, hence taping it to the outside of the bucket.

I drilled a hole in the top of a whitelabs yeast vial, filled with water and stuck my probe in there. Obviously wont' give you the temp of the fermenting wort but it accurately measures the temperature of liquid in the keezer.

Great idea! Anyone happen to know if the a419 probe is OK in water as long as it is only in about half way?

I have a growler filled with star san that my probe goes into. It's been there for a year and works for me.

It's not as good as a thermowell but better than measuring ambient.

Just remember that if you finish and go back to ambient to increase the offset to 6 degrees again.
Can u explain why going back to the 6 differential. I get the 2 different on zeroing it in on fermentation. but why have 6 degrees for ambient? Just a little confused.

It's all about thermal mass. If the probe is swinging freely inside your chamber it'll warm up inside quicker than if it is making contact with a keg, carboy, or other liquid.

If you left it on a 2 degree differential and swinging free the compressor will kick on and off much more often than you want.

At a 6 degree differential, the serving kegs and bottles in your fridge should even out at whatever temp you've chosen, or a degree or two colder. I have my fridge set to 38, so at 38 it'll kick on and drop to 32/33, and slowly warm back up *ambient*, but the liquids stay much closer to 36-38F.
