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.
Great item, always well satisfy with their products.
Thermometer fits perfect. The stopper works just as good as any other one. If you’re using carboys with a small opening and want the ability to monitor the temperature of your beer while it ferments this works well. Does not come with a thermometer.
Use it on big mouth bubbler
It doesn't fit in a carboy very well, especially if the stopper or the carboy is a bit wet. Let things dry after you sanitize. I quickly found out I needed something for a blow off tube so I pulled the thermowell out the stopper and got a carboy cap.
I use the BCS 460 and the rtd sensors that are available through Brewers Hardware. The desire fits the thermowell once the strain relief shrink wrap is removed. I did not test the more common Johnson Control probe as I don't use it anymore.
