Alkaline nitrogen analyzerBy using the principle of potentiometric titration, the electrode potential and titration volume during the titration process are recorded to find the equivalent point and the corresponding volume of standard titration solution, thereby determining the content of alkaline nitrogen in the sample. The alkaline nitrogen analyzer automatically smooths the titration curve and corrects the endpoint position to ensure the accuracy of the results.
