Overview

Add a measured amount of potassium permanganate solution and sulfuric acid solution to the sample, mix and digest them. Potassium permanganate oxidizes organic pollutants in the sample, then add a measured amount of sodium oxalate solution to reduce the remaining potassium permanganate, and drip the excess sodium oxalate back with potassium permanganate solution. The titration endpoint is determined by the oxidation-reduction potential, and finally the potassium permanganate index water quality online automatic monitoring instrument automatically calculates the potassium permanganate index value.

Principles of Measurement

Acidic potassium permanganate oxidation-reduction titration method, determination of oxidation-reduction potential endpoint:

Add a measured amount of potassium permanganate solution and sulfuric acid solution to the sample, mix and digest them. Potassium permanganate oxidizes organic pollutants in the sample, then add a measured amount of sodium oxalate solution to reduce the remaining potassium permanganate, and drip the excess sodium oxalate back with potassium permanganate solution. The titration endpoint is determined by the oxidation-reduction potential, and finally the instrument automatically calculates the permanganate index value.

Permanganate Index Water Quality Online Automatic Monitoring InstrumentMain Features

(1) The colorimetric digestion unit, injection pump precise sampling unit, and multi valve reagent switching unit are all designed with modular structures, which have lower failure rates, lower maintenance requirements, lower reagent consumption, and higher cost-effectiveness.

(2) Capable of accepting remote control commands and possessing quality control functions such as 24-hour zero drift and 24-hour range drift automatic verification, zero calibration, standard sample calibration, and standard recovery

(3) It has the function of analyzing instrument process log recording, storing raw data and operation logs for no less than 1 year.

(4) Equipped with automatic fault diagnosis function, with abnormal information recording and uploading function, such as component failure, over range alarm, over limit alarm, reagent shortage alarm and other information.

(5) Having three-level management authority

(6) After abnormal reset and power outage, the instrument automatically discharges residual reactants and returns to its initial working state. Equipped with power on alarm function, the instrument will generate alarm information when powered on again after power failure

(7) Equipped with overheat protection: If the heating temperature is too high, the heater will automatically shut down.

(8) Adopting a 7-inch touch screen and a simple operating interface, it is easy for users to learn, operate, and maintain

Typical Application

Online monitoring of permanganate index in drinking water and surface water
