I have a Milwaukee MW600 Dissolved Oxygen meter I am playing around with to assess the impact of different aspects of my brewing and fermentation process. Most of the brewing literature references Oxygen in units of ppm, but the meter reads out in mg/L. It appears in a liquid solution, mg/L is interchangeable with ppm. But I'm not sure if it should be ratio'd by the density of the fluid (wort)?
Out of the brew kettle yesterday I had 3.0 mg/L, and after 2 minutes of oxygen fed from a tank through a stone, I had 8.1 mg/L. I am trying to understand if in my 1.044 SG wort, that is 8.1 ppm of Oxygen, or 11.7 ppm.
Any experts out there on this topic?
