*Chemical Oxygen Demand (COD) is an indicator used to measure the amount of reducing substances in water. Since most reducing substances in water are organic matter, COD is commonly used as an index to assess the concentration of organic pollutants. A higher COD value indicates more severe organic pollution in the water.
*Utilizes UV absorption method, requiring no chemical reagents. The sensor integrates a self-cleaning system to effectively prevent biofouling. It also includes a built-in temperature sensor with automatic temperature compensation functionality.
*Uses modulated optical signals to reduce interference from visible light. Equipped with a turbidity measurement channel to effectively compensate for the influence of turbidity on COD readings.
*COD measurement range: 0–500 mg/L; Turbidity measurement range: 0–200 NTU
*RS485 communication interface: Supports MODBUS RTU protocol for easy connection to computers for monitoring and communication.
*Modbus communication settings: Device address can be configured, baud rate is adjustable, and temperature, turbidity, and COD readings can be retrieved from the register.
*Wide voltage power supply: Supports DC 12–30V input.
