Electrochemical-type Online COD Analyzer, HACA-2000, quantifies COD from the amount of current that is generated from oxidizing organic matter by using voltammetry method. The core technology, Composite Material Electrode, can be generated with simple polishing. Because it doesn’t require strong acid or high temperature conditions, it is easy to operate and manage as well as economical. It has less clogging due to the use of large tubes, and it can automatically check the supply of sample and reagent.

Principle
- When the optimum operating voltage is given to the composite material electrode that includes a catalyst, the catalyst that is distributed within the electrode induces oxidation reaction. Here, the measured amount of current and charge is proportional to the concentration of organic matter, it measures by converting this into COD value.
