Medical-type Oxygen Regulator with integrated flow control.
Time and rate give you an idea of how much oxygen you’re really adding to your wort. Time is easy to track. Rate, not so much, at least with typical homebrew O2 regulators. If you want more or less oxygen for your next batch, it’s mostly a guessing game.
The flow control/meter on this regulator allows you to know what rate of oxygen is going into your wort. Rate + time gives you a much better idea how much oxygen is getting into your wort and allows aids in repeatability and gives you a baseline for adjustment as you see fit.
Steve [from SlapShot Brewing] Says: “We’ve been using this model in our commercial brewery for 5 years.”
