Use in conjunction our Northern Brewer Dual-Stage Temp Controller and Fermotemp Electric Fermentation Heater for complete control over fermenting temperatures in cool environments. Fits 3, 5, 6, or 6.5 gallon glass carboys. Not compatible with Better Bottles.
Also compatible with the Thermostar® and Johnson Digital temperature controllers.
I wanted to use it in a bucket lid with grommet but the tube is too small. I was able too make it fit by adding a short piece of plastic tube over the stainless

Great but has some quirks
Great tool for temp regulation, but the stopper doesn’t fit well with an airlock. Had to improvise and secure the stopper by other means.

Must Have for Temp Controlled Fermentation
The temperature regulator comes with an attached sensor probe and wire, but you need to buy this stopper thermowell to actually get the probe down into the carboy to measure the temperature of your fermenting beer. Your probe and wire never touch the beer, never break any seals -- it all just easily slides into this long, waterproof, easy-to-sanitize tube with a sealed off end. It all runs through its own stopper which has a separate hole for the airlock. This, along w/ the temperature regulator and an electric heating wrap were all I needed to up my game for precisely controlled fermentation using tricky and magical yeasts to make more consistently delicious beer. The stopper is very firm and it can try to slide back up and out of the neck of my carboy, so use rubber bands around the collar of the carboy to hold it down.

Works Great
Paired with the NB Temp Controller and heat wrap my last two 5 gallon batches have held the intended temps for their entire fermentation within 1-2 degrees.
