It is important to note that there are different devices to measure these standards. In turn, the choice of these will depend on the use given to them in the laboratories. Its value lies in knowing the quality, physical and chemical characteristics of water.
In this sense, this quality can change and depend on different factors such as partial pressure of oxygen in the air, atmospheric pressure, water temperature, turbidity and whether there is pollution near the main source.
Therefore, the integration of dissolved oxygen meters and turbidity meters in the laboratory, whether for research, studies and analysis, measurement is an essential place, since there is nothing that can replace this important step.
