This is a diaphragm-type polarographic sensor that can be used for a wide range of residual chlorine measurement applications, including pure water, seawater, wastewater, food, and groundwater.
The Q46H/62-63 residual chlorine meter adopts a polarographic membrane sensor, allowing for the direct measurement of free chlorine, active chlorine, and combined chlorine (monochloramine) without the need for reagents. Due to its diaphragm-type sensor, it is less affected by changes in the measurement liquid or impurities, enabling the measurement of residual chlorine in electrolyzed hypochlorous water, seawater, wastewater, hot springs, and pure water. Additionally, since the electrode does not come into direct contact with the measurement liquid, it is less prone to contamination and has a long lifespan. By adding a pH sensor option, simultaneous measurement of chlorine and pH is possible. The pH correction function allows for measurements even when the pH value is high or fluctuating. It has a wide measurement range, capable of measuring low concentrations below 1 mg/L and high concentrations above 100 mg/L with a single unit. 【Features】 ■ No reagents required ■ Easy installation ■ Wide and flexible measurement range ■ Cost-effective *Demo units are available, so please feel free to inquire. *For more details, please refer to the PDF document 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.
