These are free residual chlorine meters and total residual chlorine meters using the online DPD method manufactured by Process Instruments.
DPDSense uses 520nm emitted light to detect color changes when DPD reacts with chlorine to form a pink solution. The intensity of the pink color (light absorption) is proportional to the amount of free chlorine and total chlorine present in the sample. This technology is widely accepted around the world as a standard method for online monitoring of residual chlorine levels in water. DPDSense can measure free chlorine, total chlorine, or both. *For more details, please download the PDF or feel free to contact us.*

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.
