COD Sensor, also called COD Probe, is an instrument used to measure chemical oxygen demand in water or wastewater and supports online digital transmission. Utilizing the advanced UV254 ultraviolet absorption method, it ensures fast, accurate, and reliable organic content measurements, enabling continuous online monitoring of water quality. Beyond COD, this versatile sensor can also detect parameters such as Total Organic Carbon (TOC), Turbidity Units (TU), and Total Suspended Solids (TSS), making it suitable for applications requiring comprehensive water analysis. Its dual functionality as a COD-TSS sensor or COD-TU sensor enhances its utility in environmental protection, wastewater treatment, and industrial monitoring systems.

What is COD?

Chemical Oxygen Demand (COD) is a key parameter for evaluating organic pollution in water. It measures the oxidant consumed during the oxidation of organic and certain inorganic materials in water. High COD levels signify excessive organic pollutants, which may deplete dissolved oxygen, adversely impacting aquatic ecosystems and water usability. Monitoring COD helps ensure compliance with environmental regulations and guides effective water treatment.?

How COD Sensors Work

COD Sensors use the UV254 ultraviolet absorption method to analyze water samples. Organic matter absorbs ultraviolet light when irradiated, and the intensity of absorption correlates with the organic content, allowing precise COD value calculations. This chemical-free method is efficient and ideal for a wide range of water samples, from drinking water to heavily polluted wastewater.?

Key Features of COD Sensors

• Measurement of dissolved organic matter via UV254 light absorption.
• Dual-beam LED structure ensures high accuracy for clear and polluted water samples.
• Automatic cleaning functionality reduces maintenance and eliminates chemical reagent usage.
• Continuous online monitoring enables real-time COD concentration tracking.

Applications

• Wastewater Treatment: Ensures compliance with environmental standards by monitoring COD levels.
• Drinking Water Purification: Guarantees safe and clean water for consumption.
• Industrial Processes: Monitors water quality in manufacturing and production facilities.

Conclusion

COD Sensors and Probes are essential for precise and efficient water quality monitoring. With their ability to accurately measure Chemical Oxygen Demand, they play a vital role in environmental protection and industrial applications. By adopting these advanced tools, industries and researchers can better manage water resources and reduce pollution.?
