Ranco Digital Temperature Controller (Wired)

Now you can precisely control the temperature of your fermentation, or a pump on your All-Grain System

To control ferment temperatures you can place the probe inside the space that is being cooled or heated (often a refrigerator) or you can place the probe directly into the ferment

You can change from cooling to heating mode directly from the digital control panel

The unit features an adjustable differential down to within one degree in both heating and cooling modes
