BOD sensorIt is a device used for real-time monitoring of biological oxygen demand (BOD) in water, which reflects the content of organic matter in the water and its impact on aquatic organisms. Suitable for the determination of BOD in surface water, domestic sewage, and industrial wastewater that does not have significant toxic effects on microorganisms.

　　BOD sensorBased on the principle of consuming dissolved oxygen during microbial metabolism of organic matter. The core steps include:

Microbial immobilization: Fixing specific microorganisms on the surface of the sensor to form a biofilm.

Organic matter decomposition: When the sensor comes into contact with a water sample, microorganisms metabolize organic matter in the water and consume dissolved oxygen.

Oxygen concentration detection: The decrease in dissolved oxygen is detected in real-time by the oxygen electrode and converted into a current signal.

Data correlation: The signal strength is positively correlated with the concentration of organic matter, which is converted to BOD value through a pre fabricated standard curve.

Technical advantages:

Rapid response: Compared to traditional 5-day cultivation methods, BOD sensors can complete detection within minutes to half an hour, greatly improving monitoring efficiency.

High precision: Ensure the accuracy of BOD values through pre fabricated standard curves and high-sensitivity detection of oxygen electrodes.

Real time monitoring: It can continuously monitor changes in BOD values in water bodies and promptly detect water quality issues.

Easy to maintain: Some BOD sensors have built-in ultrasonic cleaning systems, reducing manual cleaning time and extending service life.

Easy to operate: Compared with traditional BOD measurement methods, it does not require complex chemical reagents and lengthy cultivation processes, and can quickly obtain measurement results.
