An Oxygen Flow Meter with Duotight 8mm fittings - 0.1-1.5L/min.
This flow control device is designed to be used with an oxygen cylinder and regulator that can be purchased separately.
Instructions:
Attach your regulator to to the top of your oxygen cylinder. Turn pressure up to 1-10psi. Immerse diffusion stone in wort for 1-2 minutes. Then dial the flow meter up to 1.0L/min. The time it takes to saturate will depend on volume, temperature, depth of vessel, and type of stone (0.5mm recommended).
NOTE: Wort must be cold. It is extremely difficult to get oxygen to dissolve into hot wort so it's essential to cool wort completely before starting this process.
