CODMn type permanganate index online analyzer

The CODMn type permanganate index online analyzer is designed specifically for the online monitoring needs of surface water quality permanganate index. The instrument uses potassium permanganate as a strong oxidant to heat and digest organic matter in surface water. Then, a color reagent is added and its absorbance is measured at a certain wavelength to determine the concentration of permanganate index in the water sample. The instrument analysis method complies with the national standard Class A method, ensuring the accuracy and effectiveness of monitoring data.
