The concentration of dissolved oxygen in water is of utmost importance. Oxygen is the basis of life for all aquatic life. Without oxygen, toxic substances form due to anaerobic degradation. Surface water should have a minimum dissolved oxygen content of 5 mg/l.
We determine the oxygen content and oxygen saturation
