This carboy thermowell is used in conjunction with the Digital Controller, FE601A, FE610A, or FE602, to more accurately regulate internal temperature during fermentation. It is exceptionally useful during the start of fermentation when the lag between ambient temperature in the refrigerator and actual temperature in the carboy can vary greatly. Now you can keep your beer or wine within one degree of the set point on your digital controller. Designed to fit either 3, 5 or 6 gallon PLASTIC carboys or any other similarly sized opening hole. The unit comes with a 15" stainless steel thermowell and a #10 silicone stopper that will accommodate our sanitary filter, FIL90, as well. It can be used in any container with a stopper opening of this size where you need to accurately monitor and control liquid temperature.

Will not work with Johnson Temperature Controllers (FE600 or FE611) because the probes are too large.

does this work with inkbird temp controllers?
Dick Sheremeta on Sep 15, 2018
BEST ANSWER: Yes, I have used it with an ink bird controller and have no problems.
Is there a shorter version? I'm interested in this for the 3 gallon fermonster but it seems too long.
Bradley Jackson on Mar 13, 2019
BEST ANSWER: I haven't seen one that's shorter, but you can adjust this one by pulingl the tube upward through the stopper until the bottom is mid point in the fermenter.

Great Thermowells for Fermentation Control
These thermowells in conjunction with an Inkbird temp controller have greatly improved the control of my fermentation temperatures.

Works great paired with a InkBird temperature controller
The four (4) ridges provide a positive lock to my FerMonster fermenters.

This is a must have if your using an Inkbird ITC-308 and a fermonster carboy. Worked beyond my expectations.

Provides a perfect seal for my Fermonster. The thermowell is sized just right for my temperature probe, and allows for consistent temp control.

Great for Fermonster!
This is the absolute best stopper I have found for Feemonster lids! It’s soft and has ridges which hold it in place. My inkbird probe fits nicely and really helps regulate internal temp while fermenting or lagering.

Works great!
Installs firmly in my Fermonster lids. Long enough to reach 5 gallons of wort in a 7 gal fermentor. Well is wide enough to accommodate the temp sensor from my inkbird temp controller. Very satisfied with the results.

Snug fit
This stopper thermowell works perfect with my fermonster. No more taping the temperature probe to the side of the fermenter.
