The Inkbird dual stage temperature controller is an easy to use and durable controller that is perfect for home brewing. Control both heating and cooling, and set independent differentials for each to keep the exact temperature you need. This Inkbird is programmable allowing you to set up to 6 different temperatures for 6 different periods of time. This is a great way to automate the steps of your mash!
The Inkbird controller performs many of the same functions as the Ranco or Johnson but at a more affordable price, making it a great alternative for temperature control.
