CLA-7000 series Free chlorine (DPD) Online

Instrument application

Free Chlorine (DPD) online automatic analyzer is mainly used for real-time monitoring of water plants, secondary water supply of pipe network, medical wastewater, kidney dialysis medical water, food and beverage water, swimming pools, circulating cooling water, enterprise discharge wastewater and other occasions. According to the complex and changeable working conditions at the site, it is recommended that the water sample containing suspended solids be equipped with a sample supply filter system to meet the process requirements of different industries and different clients.

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.
