Application
1. Wastewater Treatment Plants
Ideal for monitoring COD and BOD levels in industrial and municipal wastewater to ensure compliance with discharge regulations. The sensor’s turbidity and temperature measurements also aid in optimizing treatment processes, such as adjusting aeration or chemical dosing, to improve efficiency and reduce operational costs.
2. Environmental Monitoring
Used in rivers, lakes, and groundwater sites to track organic pollution trends. The reagent-free design makes it environmentally safe for long-term ecological studies, while multi-parameter capabilities provide a holistic view of water quality changes over time.
3. Industrial Process Control
In manufacturing sectors like food and beverage, pharmaceuticals, and electronics, the sensor monitors process water quality in real time, preventing contamination and ensuring product consistency. Its resistance to harsh chemicals and high-temperature environments makes it a reliable choice for industrial pipelines and cooling systems.
4. Aquaculture and Agriculture
Helps maintain optimal water conditions for fish farms by measuring dissolved organic matter (COD/BOD) and turbidity, which impact aquatic life health. In irrigation systems, it monitors nutrient levels and contaminants in source water, supporting sustainable agricultural practices.
