Dissolved Oxygen Analyzer for Water Chemistry

The dissolved oxygen analyzer in water isolates the liquid being tested through an electrode membrane. Oxygen molecules pass through the membrane to undergo an electrochemical reaction, generating an electric current whose intensity is proportional to the concentration of dissolved oxygen. It is used to monitor the dissolved oxygen content in water bodies and control oxygenation conditions in wastewater treatment and aquaculture.
Selection
When selecting, consider whether the measurement range covers the actual needs, whether the electrode material's corrosion resistance is suitable for the detection environment, and whether the protection rating matches the installation conditions. Pay attention to the applicability of the calibration method and data output interfaces, and ensure that the maintenance cycle and consumable costs align with usage expectations.
