This carboy thermowell is used in conjunction with a temperature controller 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 fermentation chamber and actual temperature in the fermenter can vary greatly. Now you can keep your beer or wine within one degree of the set point on your digital controller.
