Equipped with LMS-COD100H and LMS-COD100L two models to meet different range monitoring needs, a single sensor can simultaneously measure COD, TOC, BOD, turbidity and temperature, reducing the number of equipment deployment and the complexity of the monitoring system.
The whole detection process does not need to add any chemical reagents, which not only eliminates the risk of secondary pollution to the water body, but also saves the long-term reagent purchase cost, and is more in line with the environmental protection requirements of ecological monitoring.
It has automatic turbidity interference compensation function, which can eliminate the measurement error caused by suspended particles in water; at the same time, it is not affected by chloride ions, ensuring that the detection data is accurate and stable, with the accuracy of COD and other parameters less than 5% equiv.KHP.
The integrated self-cleaning brush can automatically remove the biological attachments on the sensor surface, effectively extending the maintenance cycle, and the equipment has the characteristics of low failure rate, reducing the later operation and maintenance workload of users.
The sensor can output detection results within tens of seconds, realizing real-time monitoring of water quality; it supports RS-485 digital output and Modbus protocol, which can be quickly connected to various industrial control systems and IoT platforms, with simple operation and strong compatibility.
For municipal sewage treatment plants and industrial wastewater discharge points, the dual-model sensor can be selected according to the pollution degree of water body. It can monitor COD, BOD and other key indicators in real time to ensure that the effluent meets the discharge standards, and the turbidity and temperature data can also assist in optimizing the treatment process and reducing energy consumption.
In rivers, lakes and reservoirs, the reagent-free design of the sensor avoids damaging the ecological environment of the water body, and the multi-parameter detection can comprehensively reflect the organic pollution and turbidity changes of the water body, providing a basis for water ecological restoration and protection.
In fish and shrimp breeding ponds, the sensor can monitor the content of organic matter (COD/BOD) and turbidity of the water body in real time. When the index exceeds the standard, it can give an early warning in time, helping farmers adjust the water quality in time and maintain the healthy growth environment of aquatic products.
In food processing, pharmaceutical production and other fields, the sensor can monitor the quality of process water to prevent organic pollution from affecting product quality, and its high stability and anti-interference performance can adapt to the complex water quality environment in the production workshop.
