Dissolved oxygen sensor that achieves both high-precision measurement and low cost, with a measurable range of 0.1 PPB.
The "51100 Series" from Dextens is an electrochemical oxygen sensor capable of measuring trace amounts of oxygen in liquids and gases with high precision. It features excellent sensitivity with a detection limit of less than 0.1 ppb and can handle a wide range of saturation levels (up to 400 ppm). Its greatest strengths are its robustness and low maintenance costs. The stainless steel (316L) housing allows it to withstand high pressure and harsh chemical environments, while a design that minimizes anode wear significantly reduces maintenance frequency. Single-point calibration and data storage functions (EEPROM) also help to reduce the workload. It can be utilized in various industries such as beverages, semiconductors, pharmaceuticals, and chemicals.

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.
