What is a DO meter?

A DO meter (Dissolved Oxygen meter) is a device used to measure the amount of oxygen dissolved in a liquid. It is commonly used in water quality management, environmental monitoring, and industrial processes. The oxygen concentration is a critical indicator for the survival of fish and microorganisms and directly affects aquatic ecosystems and industrial process efficiency.

There are two primary measurement principles for DO meters: electrochemical (e.g., membrane or galvanic cell) and optical. Optical DO meters require less maintenance and offer stable long-term measurements, making them popular with modern technology. Applications include aquaculture, water quality surveys of rivers and lakes, wastewater treatment facilities, and potable water production processes.

Application of DO meter

✅Dissolved Oxygen Management in Aquaculture
In fish and shrimp farming, maintaining appropriate oxygen levels improves production efficiency and promotes growth. DO meters monitor oxygen levels in real time, preventing losses due to oxygen depletion.
✅Environmental Surveys of Rivers and Lakes
As part of water quality monitoring, DO meters measure dissolved oxygen to assess the health of ecosystems in rivers and lakes. They are vital for tracking pollution or recovery progress.
✅Operation Management in Wastewater Treatment Facilities
Wastewater treatment plants rely on DO meters to maintain the oxygen levels required for aerobic microorganisms to function effectively.
✅Quality Control in Potable Water Production
In the production of drinking water, managing dissolved oxygen levels impacts quality. DO meters ensure consistent water quality during the production process.
