Instrument application

Overview

Free Chlorine (DPD) online automatic analyzer is an online analytical instrument that uses photoelectric colorimetry for the detection of free chlorine disinfectants, which conforms to the principle of national standard free chlorine measurement. Free chlorine (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 medical wastewater, swimming pool water quality management, pipe network water 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, free chlorine in water reacts with DPD reagent to produce red compounds. At a certain wavelength, the absorbance is measured by spectrophotometry and converted into free chlorine value based on the absorbance.
