In aquaculture, dissolved oxygen is arguably the most important parameter of water quality. Most species require a minimum of 3 mg/L (ppm) DO, 8-10 mg/L (ppm) is preferable. Unlike other gases such as nitrogen, oxygen supersaturation doesn’t usually result in gas bubble disease (“pop-eye”), so high levels generally aren’t an issue.
The HI 96732 measures the content of dissolved oxygen (O2) in surface, feed, natural and waste waters in the 0.0 to 10.0 mg/L (ppm) range.
HI 96732 uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell.
