Kegland Oxygen Flow Meter with 8mm Duotight. Pure oxygen is the best way to get your yeast off to a cracking start. Simply use this high pressure and high capacity disposable tank to boost dissolved oxygen levels in your cooled wort.Oxygen is great for use with high gravity beers or pilsners where you are trying to build up a large population of yeast.We would recommend the use of a diffusion stone. These small diffusion stones create very fine bubbles of oxygen in your wort and help the oxygen to dissolve into solution faster. If you want a really nice optoin we would recommend the use of this oxygenation wand and this is a bit more erganomic as you have a rigid stainless tube to force the stone to the bottom of the fermenter rater than it floating to the surface.This flow control device is designed to be used with our oxygen cylinder and regulator that can be purchased separately.InstructionsAttach the regulator to to the top of your disposable 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.
