Description

The RS-COD-N01-2-500-EX sensor provides a modern, maintenance-reduced solution for Chemical Oxygen Demand (COD) monitoring by employing a dual-wavelength ultraviolet (UV) absorption technique. This method eliminates the need for hazardous chemical reagents, offering a safer and more environmentally friendly operation suitable for long-term, unattended deployment. The sensor incorporates real-time temperature compensation and turbidity correction algorithms to ensure measurement accuracy is maintained despite changes in water clarity and ambient conditions.

Engineered for resilience, the sensor’s housing combines corrosion-resistant engineering plastics with stainless steel components, achieving a full IP68 waterproof rating for submersion and outdoor use. Its integrated automatic cleaning system proactively mitigates biofouling and scaling, which are common challenges in wastewater and natural water bodies, thereby guaranteeing long-term stability and reducing operational downtime. The 12-30V DC wide-range input and Modbus-RTU protocol make it compatible with a vast array of industrial control and data acquisition systems.

Key Features

  • Advanced Sensing Principle: Utilizes dual-wavelength UV absorption for direct, reagent-free COD quantification, ensuring no chemical waste.
  • High-Integrity Signal Output: Standard RS485 interface with Modbus-RTU protocol enables reliable, noise-immune data transmission over long distances.
  • Robust Environmental Sealing: IP68-rated enclosure protects internal electronics from full submersion and harsh outdoor conditions.
  • Integrated System Health: Features automatic mechanical cleaning and comprehensive temperature/turbidity compensation for sustained accuracy.
  • Wide Operational Compatibility: Accepts 12-30V DC, making it suitable for both panel-powered and solar/battery-powered remote stations.
  • Optimized Mechanical Design: Constructed with corrosion-resistant materials and withstands flow rates up to 3 m/s.

Applications

  • Continuous effluent monitoring and process control in municipal and industrial wastewater treatment plants.
  • Water quality surveillance in aquaculture farms for managing organic load and ensuring healthy stock environments.
  • Environmental monitoring of rivers, lakes, and coastal waters for regulatory compliance and ecological studies.
  • Integration into smart water IoT networks for remote, real-time water quality data logging and alerting.
  • Industrial process water quality control in food & beverage, pharmaceutical, and chemical manufacturing.

Frequently Asked Questions

What is the measurement principle of this COD sensor, and does it require chemicals?

This sensor uses a reagent-free, dual-wavelength ultraviolet (UV) absorption method to determine Chemical Oxygen Demand (COD). It measures the UV absorbance of organic compounds in water at specific wavelengths, eliminating the need for hazardous chemical reagents, reducing operational costs, and minimizing waste disposal.

How do I communicate with and power this sensor?

The sensor is powered by a wide-range 12-30V DC supply. Data is transmitted via a standard RS485 interface using the Modbus-RTU protocol, allowing for direct connection to PLCs, SCADA systems, data loggers, or IoT gateways. The included cable facilitates wiring for both power and communication.

Is this sensor suitable for submersion and outdoor use?

Yes. The sensor features an IP68 waterproof rating, meaning it is fully protected against dust ingress and continuous submersion in water under defined conditions. Its construction of corrosion-resistant plastics and stainless steel makes it durable for long-term deployment in outdoor, wastewater, and marine environments.

Does the sensor correct for water turbidity, and how is maintenance handled?

Yes, the sensor includes an integrated turbidity measurement channel (0-200 NTU) and applies a correction algorithm to the COD reading, ensuring accuracy in cloudy or sediment-laden water. It also has a built-in automatic cleaning system to reduce biofouling, significantly lowering maintenance requirements compared to traditional sensors.
