Boiler Feedwater DO Analyzer

The boiler water dissolved oxygen analyzer detects the concentration of oxygen in water through an electrochemical sensor. Inside the sensor, the anode and cathode react with dissolved oxygen to generate an electric current, the intensity of which is proportional to the oxygen content. It is used to monitor the oxygen content in boiler feedwater, preventing corrosion of metal pipelines and scaling in the boiler, thereby ensuring equipment operation. It is commonly used in steam boiler systems such as those in power plants and chemical plants.
Selection
When selecting, consider a measurement range covering 0-20 ppb, with a precision error of less than 1 ppb, and adaptability to boiler water temperature and pressure conditions. The electrochemical sensor requires regular calibration, and the membrane-type structure offers strong resistance to contamination. The material should be corrosion-resistant, with an output signal compatible with the control system, and maintenance cycles and consumable costs should be moderate.
