Continuous measurement of total chlorine concentration in water using an ion-selective electrode method!
Advantages This method is a very simple chlorine measurement technique. It consumes a small amount of reagents, and chromate ions, which interfere in amperometric methods, do not cause interference here. Conductivity and calcium, which are significant interferences in the DPD method, do not interfere either. Measurement Principle – ISE Electrode Analysis is performed using the Standard Known Addition (SKA) method. Two measurements are taken, and the concentration is calculated from the difference between the two and the slope during the calibration curve creation. The reference for calculating the results is not an absolute value but the relative difference in mV, so any changes that may occur in the matrix sample are corrected by both of these lectures. This allows for the avoidance of external interference. Measurement Method It is based on the measurement of iodide. Through the reaction of chlorine, buffer solution, and potassium iodide reagent, chlorine reacts with potassium, releasing iodide. Chlorine displaces iodide. Subsequently, the ISE electrode measures the iodide, and the amount of iodide measured corresponds to the chlorine in the sample.

Company information
Sunny Trading has consistently specialized in the import and sales of automatic control and labor-saving equipment since its establishment in 1961, actively introducing the latest high-performance machinery and equipment from Europe and the United States to the domestic market. The components for production machinery that we handle are widely adopted in industries such as machinery, electrical, and chemical, and we take pride in our extensive delivery track record to national government agencies, universities, research institutions, and the aerospace industry. The delivered parts are incorporated into machines to complete large production facilities, but confirming the compatibility of the products is essential for this process. We always strive to provide appropriate products by investing technical know-how and time for specification confirmation between overseas manufacturers and our customers. Additionally, we take responsibility for follow-up services, including on-site inspections of delivered products and maintenance. Unlike general trading companies that simply import and sell goods, we pride ourselves on being a trading company with engineering capabilities. Products are commercialized as machines by manufacturers, and they are actively utilized in core industries such as semiconductors, steel, shipbuilding, aerospace, packaging, logistics, and chemicals.
