AMT/COD-400 intelligent COD sensor is a smart sensor using RS485 communication interface and standard Modbus protocol. Many organic substances dissolved in water are absorbent to ultraviolet light. Therefore, by measuring the degree of absorption of these organic matter to 254nm wavelength ultraviolet light, the content of dissolved organic pollutants in the water can be accurately measured. AMT/COD-400 intelligent COD sensor adopts two light sources, one ultraviolet light is used to measure COD content in water, and one reference light is used to measure turbidity in water. In addition, specific algorithms are used to compensate optical path attenuation and eliminate the interference of particulate suspended matter impurities to a certain extent, so as to achieve more stable and reliable measurement.

No need for reagents, no pollution, economic and environmental protection;

Small size, more convenient installation, online uninterrupted water quality monitoring;

Can measure COD, turbidity and temperature parameters;

Automatically compensates turbidity interference;

With a cleaning brush to prevent biological attachment;

Small drift, fast response, more accurate measurement;

Digital sensor, RS-485 interface, Modbus/RTU protocol.
