-Product Overview-
Based on the refractive index measurement principle, this online analyzer is purpose-built for real-time, inline monitoring of aqueous ammonia recovery solution concentration, specifically tailored for process control applications across the chemical, pharmaceutical, and food industries. The device features a built-in ultrasonic cleaning probe that automatically removes buildup from the optical window, ensuring stable long-term operation. It also offers a flow cell configuration and supports both submersible and pipeline bypass layouts. The mounting design is highly flexible, accommodating various connections such as threaded, flange, and sanitary clamp fittings, with customized interfaces available upon request.
The instrument features automatic temperature compensation, accommodating medium temperatures from 0 to 100°C, with a pressure resistance rating of up to 1 MPa, ensuring excellent environmental adaptability. For output signals, it provides a standard 4–20 mA analog output and an RS485 digital interface, with custom communication protocols available to facilitate seamless integration with control systems. The measurement unit carries an IP67 protection rating, making it suitable for humid or mildly dusty environments. Featuring a compact design and rapid response time, it enables continuous concentration monitoring—an effective replacement for manual sampling and laboratory testing that significantly enhances the timeliness and reliability of process control.
