Intelligent Online Chlorine Dioxide Analyzer W761 with AS2 Sensor for Industrial Process Water Equipped with a reliable, economical amperometric sensor for continuous measurement of free chlorine or chlorine dioxide in drinking water and process applications. With a durable PVC-U housing, it suits standard environments (≤50°C) by balancing performance and value. Its core potentiostatic three-electrode system ensures high accuracy and long-term signal stability, supporting effective disinfection control. Easy to integrate, it offers multiple electronic options: analog voltage, digital processing (analog/digital Modbus RTU), and 4-20 mA current loop. It features automatic temperature compensation and enables indefinite dry storage (no electrolyte), simplifying inventory management. As a cost-effective, reliable choice, the W761-DAS2 excels in standard water treatment—from municipal drinking water to industrial process water—where extreme conditions are absent. Application Fields Disinfection control in municipal drinking water treatment plants. Monitoring of chlorine levels in commercial and residential building water systems. Process water treatment in various industrial settings (where temperature is ≤ 50°C). Cooling water systems operating within standard temperature ranges. Technical Parameters Parameter Free Chlorine (AS2-CL), Chlorine Dioxide (AS2-CD) Application Medium Drinking Water, Process Water (up to 50°C)
