Atago PRM-100α Digital In-Line Refractometer

The Atago PRM-100α is a high-performance in-line digital refractometer meticulously engineered for real-time, continuous monitoring of liquid concentrations, Brix levels, and Refractive Index (nD) within production pipelines. Featuring an ultra-wide range of 0.00% to 100.00% Brix and a superior accuracy of ±0.05%, it is the premier solution for quality assurance in food, beverage, pharmaceutical, and chemical manufacturing. Its ability to be directly integrated into piping systems ensures meticulous control over dilution, mixing, and washing processes.

Designed with a simple two-part structure (sensor and display unit), the PRM-100α offers enhanced readability through its high-contrast color LCD panel. The prism surface is specially treated to prevent the accumulation of solids, ensuring stable diagnostics even after prolonged industrial use. With an IP67 rating, both units are fully protected against dust and water, making them suitable for rigorous CIP/SIP cleaning cycles. Equipped with RS-232C and 4-20mA analog outputs, the Atago PRM-100α seamlessly integrates into modern PLC systems to achieve maximum production efficiency.
