KCD310 Online COD Sensor no reagents no pollution small size more convenient COD turbidity and temperature


Many organic compounds dissolved in water absorb ultraviolet light. Therefore, the content of dissolved organic pollutants in water can be accurately measured by measuring the absorption of these organic compounds to 254 nm wavelength UV light. KCD310 online COD sensor uses two light sources, one ultraviolet light to measure COD content in water, the other reference light to measure turbidity of water, in addition, the optical path attenuation is compensated by a special algorithm, which can eliminate the interference of particulate impurities to a certain extent, so as to achieve a more stable and reliable measurement.



  • No reagents, no pollution, economic and environmental protection
  • Small size, more convenient installation, online continuous water quality monitoring
  • Cod, turbidity and temperature can be measured
  • Automatically compensates for turbidity interference
  • With a cleaning brush to prevent biological adhesion
  • Small drift, fast response, more accurate measurement
  • Even long-term monitoring is extremely stable
  • Maintenance-free, long service life and low cost
  • Digital sensor, RS-485 interface, Modbus/RTU protocol
  • Low-power electronics, anti interference design

Tips:Can I use my COD results to predict my BOD?

YES. Although COD should be considered an independent test from BOD, and will generate a higher concentration reading than BOD for a particular wastewater sample, it is generally accepted that COD and BOD share an empirical relationship. Extensive observation of the COD and BOD levels on the same wastewater has shown that the COD to BOD ratio of a particular wastewater will remain constant over time.

For example, food processing wastewater will generally have a COD:BOD ratio of ~2:1, while textile wastewater that can contain dyes will often have a much higher COD:BOD ratio of ~5:1.

To establish the COD:BOD ratio for your wastewater, simply have both COD and BOD run on several wastewater samples. Divide the COD concentration by the BOD concentration for each sample and average the results. For example, below is the COD:BOD ratio developed using three wastewater samples from a food processor:

The important point is that once you have established an average COD:BOD ratio for your wastewater stream, then the relatively simple and quick COD test can be used to predict BOD with relative reliability.
