Water Quality Dissolved Oxygen Analyzer

The water quality dissolved oxygen analyzer detects the dissolved oxygen content in water through electrochemical or optical sensors. The electrochemical method uses a membrane-covered electrode to generate a current signal, while the optical method is based on the principle of fluorescence quenching. It is used to monitor the oxygen content in water bodies, ensuring the survival of aquatic organisms and controlling wastewater treatment processes.
Selection
Select instruments based on electrochemical or optical principles according to the measurement environment. Ensure the measurement range covers the conventional 0-20 mg/L range, with accuracy meeting the basic requirement of ±0.1 mg/L. Pay attention to matching the sensor protection level with the water environment, and regularly replace and maintain the electrode membrane. Portable instruments are suitable for field testing, while online instruments are used for continuous monitoring.
