MDS-7200-NMP (N-Methyl-2-pyrrolidone) Refractometer

-Product Overview-

The MDS-7200-NMP is an inline refractometer specifically designed for real-time monitoring of NMP liquid concentration. It is engineered to eliminate the detection lag and measurement fluctuations associated with traditional manual sampling. Featuring a submersible installation design, the device can be deployed directly on the factory floor. By default, it collects data continuously at a frequency of 1 Hz, delivering second-level response to concentration changes and helping users track process dynamics in real time.

Based on the refractive index measurement principle, the instrument covers an NMP measurement range of 0.00% to 100.00%, while simultaneously detecting both refractive index and temperature. With strong environmental adaptability, it operates stably in ambient temperatures from 0°C to 60°C. The measurement unit features an IP67 protection rating and 1.0 MPa pressure resistance, making it suitable for most production conditions. It provides a 4–20 mA analog output and RS485 digital output, allowing flexible integration of concentration signals with control systems or data platforms. The device also supports various mounting customizations—including threaded, flange, and sanitary clamp connections—to meet diverse on-site requirements.

Through fully automated, uninterrupted online monitoring, the system delivers a one-stop solution to improve NMP production control efficiency, reduce manual intervention, and stabilize process quality, helping enterprises achieve cost reduction, efficiency gains, and refined production management.

-Key Features & Benefits-
