Maintaining the right dissolved oxygen (DO) level is essential for healthy aquatic environments, efficient aquaculture operations, and reliable water-quality monitoring. The FDO-300 Portable Optical Dissolved Oxygen Meter provides a practical solution for professionals who need accurate and convenient dissolved oxygen measurements in the field or laboratory.
Why Dissolved Oxygen Matters
Dissolved oxygen refers to the amount of oxygen available in water. It plays an important role in supporting aquatic organisms, managing aquaculture systems, and monitoring overall water quality.
Low or unstable oxygen levels can affect fish and other aquatic organisms and may indicate changes in water conditions. Regular DO monitoring helps operators make informed decisions and respond to changes more effectively.
Meet the FDO-300
The FDO-300 is designed for users who need portable, reliable, and accurate dissolved oxygen measurement without the complexity of larger monitoring systems.
Its optical DO technology allows users to measure oxygen levels across a wide range, making the meter suitable for various water-quality applications.
