Dissolved oxygen (DO) is one of the most vital indicators of water quality. High DO levels improve the taste of drinking water, but this can cause corrosion in water pipes. Alternatively, low dissolved oxygen levels below 5.0 mg/L stress aquatic life and creates hypoxic conditions.
What Influences Dissolved Oxygen Levels In Water?
Many factors can influence dissolved oxygen levels in the water, which in turn affects the water quality. These include the following:
Diffusion
Aeration
Photosynthesis
Respiration
Decomposition
Measuring Dissolved Oxygen
Measuring DO levels is necessary to assess water quality. While there are many ways to test DO. Measuring DO levels is necessary to assess water quality. While there are many ways to test DO, fluorescence Dissolved Oxygen Sensor is the most accurate.
Dissolved oxygen probes measure the amount of oxygen that diffuses across a permeable or semi-permeable membrane inside the DO probe. When the probe detects oxygen, a chemical reduction reaction produces an electrical signal. The electrical signal is then displayed on the meter, giving you an accurate DO reading.
