This stainless thermowell is perfect for inserting our Keg King Dual Controller probe into, and then inserting into a glass carboy (does not fit the Vintage Shop or Better Bottle carboys) to monitor liquid temperature. The stainless probe is 14" long, and attached to a #6.5 stopper with an extra hole drilled for an airlock. Fits carboys with openings between 1.2" and 1.5" in diameter. Fits all the glass carboys we sell (except the 1 gallon).
Great for use with Brew Belt Heater or Brew Heater Pad (see links below). Also works with Ranco and Johnson Controls brand digital temperature probes (not the analog grey Controller model with the capillary tube). Made in USA.
Fits probes up to ¼" (6.5mm) in diameter.
