Instrument application

Overview

ClO2A-7000 series Chlorine Dioxide (DPD) online automatic analyzer is an online analytical instrument that uses photoelectric colorimetry for the detection of Chlorine Dioxide disinfectants, which conforms to the principle of national standard Chlorine Dioxide measurement. ClO2A-7000 series Chlorine Dioxide (DPD) online automatic analyzer has the characteristics of

simple structure, easy maintenance, long maintenance intervals, accurate test data, and good stability. It can be used in tap water,sewage water plant and other occasions. At the same time, to provide you with better application solutions,, we have developed a water sample supply system that makes the operation of the instrument more stable through a large number of operating practices, so that the online analytical instrument can operate accurately and stably.

Instrument measurement principle:

Under weakly acidic conditions, Chlorine Dioxide in water reacts with DPD reagent to produce red compounds. At a certain wavelength, the absorbance is measured by spectrophotometry and converted into Chlorine Dioxide value based on the absorbance.
