Vaisala, a global expert in measurement instruments and intelligence for critical environments, will showcase inline liquid concentration measurement solutions at PACK EXPO International 2026, held October 18–21 at McCormick Place in Chicago. At Booth LU-7559, Vaisala will demonstrate the Polaris™ PR53AC Sanitary Compact Process Refractometer connected to the Indigo520 Transmitter. Together, the solution provides continuous, real-time measurement of Brix and liquid concentration for food and beverage, pharmaceutical and biotechnology manufacturing processes.
For food and beverage producers, Vaisala Polaris brings liquid-concentration measurement directly into the process. Continuous inline data can reduce reliance on manual sampling and laboratory analysis. It can also help manufacturers maintain product consistency, optimize ingredient use, reduce waste and improve production efficiency.
The PR53AC has a measurement range of 0-100% for Brix and other liquid concentrations. Using refractive index measurements, the PR53AC provides reliable measurement in demanding applications, with performance unaffected by air bubbles, color, pulp, or suspended solids. The compact refractometer supports beverage blending, juice and soft drink production, dairy processing, syrup preparation, cooking, evaporation, extraction and fermentation. It also supports product interface detection and organics monitoring in wastewater or side streams.

For pharmaceutical and biotechnology manufacturers, continuous inline concentration measurement can provide timely process insight from development through commercial production. The technology supports applications including API production, reaction monitoring, crystallization, solvent exchange, filter cake washing, pharmaceutical fermentation and protein concentration. Real-time process data can support stronger process understanding, quality control and more consistent production.
Designed for hygienic processing environments, the PR53AC is 3-A Sanitary and EHEDG certified. It is compatible with clean-in-place and sanitation-in-place procedures. The instrument installs directly in pipes, tanks and vessels without a bypass arrangement. Its no-moving-parts design supports low-maintenance operation.
The industrial-grade Indigo520 Transmitter provides access to live measurement data, settings and process parameters through an optional touchscreen display and web interface. Its IP66-rated metal enclosure supports demanding industrial environments. The transmitter also provides data logging, wash control, trend monitoring and concentration-curve management. It displays measurements locally and transmits process data to automation systems through configurable analog outputs, relays or Modbus TCP/IP over Ethernet.
Visit Vaisala at Booth LU-7559 to learn how the Polaris PR53AC and Indigo520 can help food and beverage, pharmaceutical and biotechnology manufacturers improve real-time process visibility, quality control and resource efficiency.
