This carboy thermowell is used in conjunction with the Digital Thermostat 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 the 5, 6 or 6.5 gallon carboys

Customer Reviews

Sits very loose in the neck of a carboy Review by Phillip
I picked this up so that I could have a temperature probe inserted into the hollow tube that connects to my two stage temp controller. At the same time, I also picked up the stainless steel blow off tube to go with this.

The stopper does not fit very snug. You have to push it pretty far down into the mouth of the carboy and even then, it works its way back up to the top where it sits very loosely. This stopper is not the same as the other rubber stoppers that fit very nicely into the mouths of the carboys.

At the moment I am trying different ways to keep this seated down snug, but it's becoming more of a hassle than it's worth.

I would not recommend this item. (Posted on 2/7/2017)
