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.
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.
Very nice and fits well into my sovereign stainless fermenter. Only problem is. Can the inside of the probe get wet?
Exactly what I wanted. Works great on Big Mouth bubbler
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.
