DISSOLVED OXYGEN PHOTOMETER
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.
HI 96732 is supplied with (2) sample cuvettes with caps, 60 mL glass bottle with stopper, 9V battery and instructions. CAL CHECK™ standards and reagents sold separately.
