With the Johnson thermostat any freezer can be turned into a sophisticated lagering cooler. Place the temperature probe into the freezer, plug the thermostat into a wall electrical outlet, and then plug the freezer into the Johnson. Set the thermostat to the desired temperature. No more waiting for winter to brew favorite lagers.
This thermostat has a range from 20 F to 80 F (-7 C to 27 C).
