-Product Overview-
The MDS-7200-Ace-HX Acetone-Hexane Concentration Refractometer is engineered based on the refractive index measurement principle, purpose-built for real-time, inline monitoring of acetone-hexane solution concentrations in chemical, pharmaceutical, and food processing industries. Equipped with a built-in ultrasonic cleaning probe, the device automatically removes buildup from the optical window to ensure long-term stable operation. It offers versatile installation options—including a flow cell configuration—and supports submersible or pipeline bypass layouts with flexible connections such as threaded, flanged, and sanitary clamp fittings.
Featuring automatic temperature compensation, the instrument accommodates medium temperatures from 0 to 100°C (customizable up to 150°C) and a pressure resistance rating of up to 1 MPa. For seamless integration with control systems, it provides a standard 4–20 mA analog output and an RS485 digital interface, with custom communication protocols available upon request. The measurement unit carries an IP67 protection rating, making it highly reliable in humid or mildly dusty environments. By delivering continuous concentration monitoring, it effectively replaces manual sampling and laboratory testing to significantly enhance the timeliness and reliability of process control.
