Water quality monitoring is essential for aquaculture, wastewater treatment, environmental research, and many other applications where dissolved oxygen (DO) levels directly affect system performance. Reliable measurements help operators understand changing water conditions and make timely decisions.
The FDO-300 Portable Optical Dissolved Oxygen Meter provides a practical solution for fast and dependable dissolved oxygen measurement in the field, laboratory, and treatment environments.
Why Dissolved Oxygen Matters
Dissolved oxygen is one of the most important indicators of water quality. In aquaculture, sufficient oxygen supports healthy aquatic organisms and helps maintain stable growing conditions. In natural waterways, DO measurements can provide valuable insight into ecosystem conditions. In wastewater treatment, monitoring oxygen levels can help operators manage biological treatment processes more effectively.
Because oxygen levels can change with temperature, biological activity, water movement, and other environmental factors, having a portable meter allows measurements to be taken directly where they matter.
Meet the FDO-300
The FDO-300 is a portable optical dissolved oxygen meter designed for convenient and accurate water-quality measurements.
Its optical measurement technology helps simplify DO monitoring while its portable design makes it suitable for on-site measurements. Whether you’re checking an aquaculture system, evaluating environmental water, or monitoring a treatment process, the FDO-300 is designed to provide useful readings when and where you need them.
Key Features
Wide Measuring Range
The FDO-300 measures dissolved oxygen from:
