Aeration Unit

Specification:

• An aeration unit to permit the study of oxygen transfer characteristics of diffuse air systems.
• Comprising a 24.5 litre open tank with variable speed motor driven stirrer paddle and pumped air supply, via a valve and flow meter, to a diffuser.
• Sparger, single and treble air stone difusers are included in the supply.
• A battery powered dissolved oxygen meter provides intrumentation including direct reading of water temperature.
