This instrument uses potassium permanganate (acidic) titration method to measure water samples. Dissolve and oxidize certain organic and inorganic reducing substances in the water sample using an acidic potassium permanganate solution at 96 ℃, and measure the remaining amount of potassium permanganate at 525nm. The reduction of potassium permanganate is directly proportional to the consumption of organic matter.
Modular design allows each component to operate independently, improving the efficiency of the instrument;
