Add a known amount of potassium permanganate and sulfuric acid to the sample, and heat it for a certain time under high temperature. Potassium permanganate oxidizes some organic and inorganic reducing substances in the sample. After the reaction, add excess sodium oxalate to reduce the remaining Potassium permanganate, use potassium permanganate standard solution to titrate back to excess sodium oxalate, and calculate the permanganate index in the sample.

Characteristics:

Valve components selection. It can select the reagent sampling sequence, with flexible channels, variable functions, minimum dead volume, easy maintenance, long service life and other advantages.

Printing function. It can be connected to a printer (optional order) to print the measured data in time.

It adopts 7-inch touch screen, with simple operation interface, easy for users to learn, operate, and maintain.

Super large data storage capacity. It can realize storage of historical data for no less than 5 years (measurement interval is 1 time/1h), which greatly meets the needs of customers.

Automatic leakage alarm function. When reagent leakage occurs, the instrument will automatically alarm to remind the user to perform maintenance.

Light signal recognition function to ensure high accuracy of quantification.

Simple and convenient chemical reagents maintenance. The reagents can be replaced once a month, which greatly reduces the maintenance of the user.

U disk one-click upgrade. The software update is much easier.
