VAISALA POLARIS

Polaris™ PR53AC Sanitary Compact Process Refractometer

The Vaisala Polaris PR53AC sanitary compact process refractometer is designed to measure liquid concentrations, such as Brix, inline.

Applications include food, beverage, dairy and brewery industry customers, and OEMs. 3‑A and EHEDG certifications ensure that all hygienic demands and safety requirements are met.

Easy to install directly in pipelines with a sanitary clamp and optional flow cells.

• Reliable optical concentration measurements with refractive index
• Brix, Total Solids, Oechsle, Baume, Plato, and more than 500 concentration curves
• 3‑A and EHEDG certified
• 3‑A and Type N sanitary couplings
• Measurement not affected by bubbles, particles, suspended solids, or color
• Various flow cells available
• Indigo520-compatible
• Built-in 4–20 mA and Modbus RTU outputs
  • The optical measurement is based on the refractive index (RI).
  • The RI can be measured from practically any liquid and it responds to dissolved material.
  • Bubbles, particles, or fibers in the process do not affect measurement.
  • The outstanding long-term stability provides years of accurate, continuous, fast, and stable measurement for concentration of sugar (Brix) and various other chemical concentrations directly in the process stream.
