Continuous and real-time measurement of COD in water without reagents!
It is possible to continuously and in real-time measure COD (Chemical Oxygen Demand) without the use of reagents. 【Measurement Method】 This analytical device consists of a UV 254nm light source, a sample cell, and a light detector. The light incident on the sample is absorbed by components in the water, and by measuring the transmitted light with the detector, the COD equivalent value based on the absorbance in the sample is calculated. The light source uses a long-life LED and achieves high measurement accuracy through a 180° optical system compliant with international standards. Additionally, the automatic wiper mechanism removes bubbles and dirt that adhere to the optical window, maintaining a clean state at all times, which ensures precision and reduces maintenance load. 【Features】 ■ Continuous and real-time measurement of COD without reagents ■ All-in-one compact housing with built-in transmitter and sensor ■ Equipped with an automatic wiper to keep the optical window clean and maintain stable measurements ■ Equipped with RS485 digital communication ■ Low power consumption design, ideal for outdoor and long-term operation

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.
