How to measure dissolved oxygen. Dissolved oxygen is measured using a dissolved oxygen meter. The best method is to take the measurement in the field at the same time each day because DO concentrations can vary throughout a 24 hour period.issolved oxygen (DO) is a measure of the quantity of free oxygen molecules in water.
As the temperature goes up, water releases some of its oxygen into the air. Water also holds less dissolved oxygen at higher elevations because there is less pressure. Solubility of dissolved oxygen also decreases as salinity increases. Dissolved oxygen refers to the amount of oxygen contained in water. Oxygen has limited solubility in water usually ranging from 6-14 mg/L. Dissolved oxygen reflect an equilibrium between oxygen producing processes and oxygen consuming processes.
