Manganese-type Online COD Analyzer, HACA-3000, is measuring equipment that automated the Standard Water Pollutant Testing Method. HACA-3000 has a simple configuration that has adopted the 5-port control valve to enable inflow of fixed quantity of sample and reagent for the purpose of accurate measurement. It has less clogging due to the use of large tubes, and it can automatically check the supply of sample and reagent. It has extensive applications in the management of drinking water quality, wastewater, industrial effluent, groundwater, rivers, and ecosystem samples.

Principle
HACA-3000 measures COD by using the potassium permanganate method. Potassium permanganate method is a method that displays the pollution level of a sample by heating KMnO4 and letting it react to the heat for a certain time, and then converting the amount of oxygen that responds to the amount of KMnO4 that is consumed when the organic matter in the sample is oxidized.
