Dissolved oxygen (DO) is measured to determine the amount of gaseous oxygen dissolved in water. It is essential to monitor the DO levels in aquaculture to ensure there is enough DO in the water, as oxygen is necessary for growth and metabolism of aquatic organisms. DO is also important in boilers and cooling towers to prevent corrosion of the pipes.


From Chemical Test Kits to portable Photometers and benchtop meters, Hanna offer a wide range of instruments suitable for accurate determination of DO levels.
