Dissolved Oxygen(DO) Meter

What is Dissolved Oxygen Meter?

Dissolved oxygen meters are analytical instruments used to measure the amount of oxygen dissolved in a unit volume of water. Oxygen dissolves poorly and can only exist in water at low concentrations however it is still is essential for the respiration of a wide variety aquatic animals and bacteria. The accurate measurement of dissolved oxygen is critical to processes such as the making of compost tea, testing water quality, sewage treatment, river monitoring, fish farming, wine making many other applications where the amount of dissolved oxygen in water is important.
