Vaisala unveiled the process refractometer platform PolarisTM. The products are designed to optimize industrial manufacturing processes and enhance productivity in various industries. The platform brings together the company’s long-term measurement excellence with the latest liquid measurements expertise.

Real-time measurement 

Polaris product family is designed to work seamlessly, out of the box, with Vaisala’s Indigo520 transmitters for process refractometers, combining liquid and gas measurement possibilities. The process refractometers are used for inline liquid concentration measurements for various industries, installation positions, and applications. The real-time measurement data they produce of the process enable advanced and accurate process control enhancing the manufacturing process. Vaisala's process refractometer can measure various liquid concentrations through refractive index, inline, real-time. Processes include evaporation, distillation, fermentation, blending, filtration, crystallization, interface detection, dilution, extraction and more. There are versions designed for hygienic applications in food and beverage, and life science industries, and for OEM customers. They measure Brix and other concentrations inline accurately and in real time (PR53AC/PR53AP). Another version, PR53GP, is designed for oil & gas, chemical, sugar, and sweetener industry. It measures concentrations of sugars, acids, alkaline solutions, alcohols, hydrocarbons, solvents, and in various other solutions. Vaisala Polaris™ PR53GC Process Refractometer is optimized to chemical industry, where it measures concentrations of acids, alkaline solutions, alcohols, hydrocarbons, solvents, and various other solutions. But even more versions for different specific applications are available.

Versatile transmitter

The Vaisala Indigo520 Transmitter for process refractometers allows connectivity with all Indigo products including the liquid and gas measurements alike, for parameters such as temperature, relative humidity, carbon dioxide, and vaporized hydrogen peroxide. Indigo520 transmitter also provides user interface and data visualization through touch panel display, data logging, wash control, settings, and service updates.
