Description
In aquaculture, dissolved oxygen is undoubtedly the most important parameter of water quality. Most species require a minimum of 3 mg/l (ppm) DO, 8-10 mg/l (ppm) preferably. Unlike other gases such as nitrogen, oxygen supersaturation does not usually result in pop-eye disease, so such high levels are usually not a problem.
The HI 96732 measures dissolved oxygen (O2) content in surface, natural feed, and wastewater at 0.0 to 10.0 mg/l (ppm).
The HI 96732 uses a unique secure closure system to ensure that the cuvette is in the same place each time it is placed in the measuring cell.
Dissolved oxygen analysis measures the amount of gaseous oxygen (O2) dissolved in an aqueous solution. Dissolved oxygen is one of the most important parameters in aquatic systems. This gas is an indispensable requirement for the metabolism of aerobic organisms and also influences inorganic chemical reactions. Therefore, knowledge of the solubility and dynamics of oxygen distribution is essential for the interpretation of biological and chemical processes in water bodies. Oxygen is introduced into the water by diffusion from the surrounding air, by aeration (rapid movement), and as a waste product of photosynthesis. The amount of oxygen (or any gas) that can be dissolved in pure water (saturation point) is inversely proportional to the temperature of the water; the warmer the water, the less dissolved oxygen.
