Portable On-line Chemical Oxygen Demand System

Chemical Oxygen Demand (COD) which reflects the total pollution load of waste water discharges is considered to be one of the most important parameters in waste water and waste chemical treatment processes. However, the determination of COD is often difficult, requiring frequent sampling and at least 2-3 hours of boiling by the standard titration method. The Portable on-line COD system has several advantages over traditional method:

  • Fast COD measurement: estimate 20 minutes
  • Wide application range (50-12000 ppm) with less than ±3% error
  • Intelligent control and operation
  • No secondary environment pollution
  • Compact/portable mechanical design
