(THM510) What an idea! A wall-plate switch cover with a built in digital thermometer. Allows you to monitor the ambient room temperature in the area you do your fermentations.

Helps to eliminate the chance of having a stuck fermentation caused by cooler room temperatures. Or, having off-flavors in your wine or beer from having too warm of fermentation temperatures. Just takes a minute to install, just put it in place of your current wall-plate cover. You don`t have to touch a single wire. Battery included.
