Description The product adopts the detection principle of the potassium permanganate oxidative titration method. The pretreated water sample is oxidized and digested by potassium permanganate under constant temperature conditions, and then reduced by adding excess sodium oxalate solution and titrated with potassium permanganate solution. For reducing agents, the titration endpoint is judged by absorbance or redox potential, and the volume of potassium permanganate volume calculates the permanganate index value dropped back. The instrument has two detection methods of acidity and alkalinity. When the chloride ion concentration in the solution is high, the alkaline potassium permanganate oxidative titration method can be used to eliminate the interference of chloride ions in the solution.
