PR-53AC

Vaisala Polaris PR53AC Sanitary Compact Process Refractometer

Inline Liquid Concentration Measurement for Hygienic Applications.

The Vaisala Polaris PR53AC is a sanitary compact process refractometer engineered for inline measurement of liquid concentrations, such as Brix, in hygienic environments. It is specifically designed for the food, beverage, dairy, and brewery industries, as well as for OEMs. This refractometer adheres to stringent hygienic and safety standards, holding 3-A and EHEDG certifications. Its optical measurement principle relies on the refractive index (RI), which responds to dissolved material and remains unaffected by bubbles, particles, suspended solids, or color in the process stream. The PR53AC offers exceptional long-term stability, ensuring years of accurate, continuous, fast, and stable measurements without the need for moving parts or regular maintenance. It can be easily installed directly into pipelines using a sanitary clamp and optional flow cells, and is compatible with the Indigo520.
