Continuous and real-time measurement of sulfide (S²⁻) in water without the need for reagents!
It is possible to continuously and real-time measure sulfide (S²⁻) without using reagents. 【Measurement Method】 Continuous measurement of sulfide is performed using an ion-selective electrode with a specific membrane that is selective for sulfide ions. This membrane creates charge separation between the electrode surrounded by water and the internal filling solution. The charge is measured as voltage and changes in response to concentration variations in the water adjacent to the water membrane. Compared to conventional colorimetric methods, it has many advantages, including faster response time, greater accuracy, ease of operation, and no need for reagents. 【Features】 ■ Continuous and real-time measurement of sulfide (S²⁻) 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

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.
