Online Process DO Analyzer

Online dissolved oxygen meters detect the concentration of dissolved oxygen in water through electrochemical or optical sensors. The electrochemical type uses a membrane-covered electrode to generate current signals, while the optical type operates on the principle of fluorescence quenching. They are used for real-time monitoring in applications such as wastewater treatment and aquaculture to ensure stable oxygen levels in water bodies.
Selection
When selecting an online dissolved oxygen meter, it is essential to consider whether the measurement range covers 0-20 mg/L, the accuracy meets the requirement of ±1%, and the protection rating is suitable for the on-site environment. The sensor type, whether electrochemical or optical, should be determined based on the maintenance frequency. Additionally, the output signal must be compatible with the control system, and the calibration method should be simple and reliable.
