Portable COD Analyzer with Digester

Chemical Oxygen demand is defined as the amount of oxygen required for the oxidation of all the organic compounds present in the water sample.  

The portable, microprocessor based Uniphos COD analyzer operates on the non-dispersive absorption principle to measure COD of waste / effluent water samples. This easy to use battery operated analyzer features an easy to use intuitive interface and has in-built data logging facility as standard. The stored data can either be exported to a computer or printed as a report to a RS-232 printer.
A COD Digester is also provided with the COD analyzer for digestion of the water sample mixed with reagents. It is a robust instrument capable of accommodating 25 vials at a time. A PID controller in the digester ensures that all the samples are heated precisely to 150oC.  

Application

  • Municipal Water
  • Industrial Process Fluids
  • Drinking Water
  • Wastewater and Effluent Water
  • Ground and Surface water

Features

  • Rugged, portable design with no moving parts
  • Computer and printer interface
  • Reduction in space and operator time.
  • Total digestion time is 2 hours, but operator analysis time is less than 2 minutes.
  • Reduces analysis cost.
