Continuous measurement of arsenic concentration in water is possible!
Measurement Method – Colorimetric After placing the sample in the measurement cell, reagents are added to adjust the solution to the desired conditions (pH, valence, etc.). A blank is then performed to correct for disturbances in temperature and turbidity. After that, the final reagent is added, which reacts with the solution to produce a color that is measured. Measurement Principle This method is based on the oxidation of As(III) to As(IV). Subsequently, when the necessary reagents are added, As(IV) reacts with molybdate to form a molybdenum arsenic complex. This complex is reduced and exhibits a blue color, which is proportional to the arsenic concentration.

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.
