HACA-4000 is a measuring instrument that automates potassium permanganate method of water pollution test method. The potassium permanganate method measures the COD by adding a certain amount of oxidizing agent (potassium permanganate) to the sample, heating it, converting the amount of potassium permanganate consumed in the oxidative decomposition of the organic matter to the corresponding amount of oxygen consumed. At this time, the appropriate amount is calculated by recognizing the rising point of the ORP value by the addition of potassium permanganate as the proper end point. The HACA-4000 is a new product from KORBI that not only improves performance by applying patented technology and preliminary measurement logic, but also has sophisticated design and user-friendliness.
