Product Introduction
The working principle of the potassium permanganate index water quality online monitoring instrument is mainly based on the oxidation-reduction reaction of potassium permanganate. The instrument uses acidic potassium permanganate as an oxidant to oxidize organic matter in the water sample, and determines the permanganate index by measuring the color change or current change generated during the reaction process.
