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.
The CLA-7000 series Total Chlorine (DPD) Online Automatic Analyzer is a comprehensive online analytical instrument that utilizes photoelectric colorimetry to accurately detect free chlorine, total chlorine, and other disinfectants. It adheres to the national standard for total chlorine measurement, ensuring accurate and reliable results.
The CLA-7000 series analyzer offers a range of notable features, including a straightforward design, easy maintenance, extended maintenance intervals, precise test data, and exceptional stability. It is well-suited for a range of applications, including medical wastewater treatment, swimming pool water quality management, and pipe network water monitoring.
To further enhance its practicality, we have developed an advanced water sample supply system that streamlines instrument operation. This system has been refined through rigorous operational testing to ensure the online analyzer functions with unparalleled precision and dependability.
The Analyzer’s Measurement Principle:
Under slightly acidic conditions, free chlorine in water reacts with DPD reagent to produce red compounds. The absorbance of these compounds is measured at a specific wavelength and converted into residual chlorine values. Additionally, when excess KI is present, elemental chlorine, hypochlorous acid, hypochlorite, and chloramine react with the DPD reagent to form a red compound. The absorbance of this compound is measured and converted into total chlorine values. This multi-index detection capability makes the CLA-7000 series analyzer a versatile tool for a range of water quality monitoring applications.
