Dissolved oxygen (DO) is one of the most important indicators of water quality. It is essential for the survival of fish and other aquatic organisms. Oxygen dissolves in surface water due to the aerating action of winds.Oxygen is also introduced into the water as a byproduct of aquatic plant photosynthesis.

​

When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive.

​AquaPacific Dissolved Oxygen (DO) kit uses Titration method to estimate Dissolved Oxygen and is calculated in mg/l.
