feature of dissolved oxygen meter
The dissolved oxygen meter measures the amount of oxygen dissolved in an aqueous solution. Oxygen dissolves in the water through ambient air, air flow, and photosynthesis.
Dissolved oxygen is consumed in water by breathing and decomposition, and is mainly supplemented by air and photosynthesis. The amount of oxygen in the water depends mainly on the temperature. The oxygen concentration in warm water is lower than that in cold water. However, excessive dissolved oxygen levels can be harmful to plants and animals.
