Grainfather Conical - Digital Temperature Controller
The Grainfather digital Temperature Controller replaces the temperature display. With this you can control the heating and the cooling (if you have the Grainfather Glycol Chiller) of your fermenter by dialing in a temperature or even setting a temperature schedule (can set up to 5 stages). This snaps on easily via magnets and pogo pins with no extra cords or clutter.
