I have my last piece of homebrewing equipment to sell. Its a ranco etc 111000 wired up to control a fridge/freezer. I have also installed a 6ft lead with a 12" stainless probe. It sits in a carboy cap along with a blow off hose. This monitors fermentation temperatures in the middle of the carboy for more accurate temp control.
The way it is wired now, just plug in your fridge and your ready to go.
Comes with 8ft-ish power wire and 6ft probe wire. Carboy cap and blow off tube.
75 dollars plus shipping.
