Instrument application
Total 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 on 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 customers.
Overview
CLA-7000 series Total chlorine (DPD) Online automatic analyzer is a multi-index online analysis instrument that uses photoelectric colorimetry to detect Free chlorine, Total chlorine and other disinfectants, and conforms to the national standard total chlorine measurement principle. CLA-7000 series Total chlorine (DPD) Online automatic analyzer has the characteristics of simple structure, easy maintenance, long maintenance interval, 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, through a large number of operating practices, a water sample supply system that makes the operation of the instrument more stable has been introduced to provide you with better application solutions, 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 and converted into residual chlorine based on the absorbance. In the presence of excess KI, elemental chlorine, hypochlorous acid, hypochlorite and chloramine react with the DPD reagent to form a red compound, and the absorbance is measured according to The absorbance is converted to total chlorine.
