The new platform of inline process refractometers in Vaisala’s portfolio introduces the first fully inhouse developed refractometer series to product platform that combines both liquid and gas measurement capabilities.

Vaisala has strengthened its industrial product ecosystem by unveiling the process refractometer platform, Polaris. The products are designed to optimise industrial manufacturing processes, product quality, enhance productivity, and save resources, energy, and time in various industries and hundreds of industrial applications.
“We are thrilled to introduce Vaisala Polaris which bundles together Vaisala’s measurement and application expertise, innovative technology, world-leading measurement capabilities, and industry-known robustness. All this boosted with Vaisala’s state-of-art production system, which brings added value to customers through product quality and short delivery times,” commented product manager Jarkko Ruonala from Vaisala.
The launched refractometer platform has further strengthened Vaisala’s modular Indigo measurement ecosystem.
Ruonala said: “The Polaris product family is designed to work seamlessly, out of the box, with Vaisala’s Indigo520 transmitters for process refractometers. By unveiling the Indigo connectivity to our refractometer customers, we are bringing more choices to their fingertips. Combining liquid and gas measurement possibilities is what makes the platform utterly unique.”
Vaisala Polaris process refractometers
Vaisala’s 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. Consequently, with the improved process efficiency the energy and resources are used less, the end-product quality improves which brings less waste and better productivity and yield to the customers.
Vaisala’s process refractometer can measure various liquid concentrations through refractive index, inline, an in real-time. Processes include evaporation, distillation, fermentation, blending, filtration, crystallisation, interface detection, dilution, extraction and more.
Vaisala Polaris PR53AC process refractometer and Vaisala Polaris PR53AP process refractometer are designed for hygienic applications in the food and beverage, and life science industries, and for OEM customers. They measure Brix and other concentrations inline accurately and in real time.
Vaisala Polaris PR53GP process refractometer is for the oil and gas, chemical, sugar, and sweetener industry. It measures concentrations of sugars, acids, alkaline solutions, alcohols, hydrocarbons, solvents, and in various other solutions.
For pulp and paper industry, Vaisala Polaris PR53SD SAFE-DRIVE process refractometer measures the total dissolved solids and other concentrations. The unique design of the retractor tool and the isolation valve ensures operator safety during insertion and removal of the sensor, which can be done without depressurizing the line.
The Polaris product range will be globally available during 2023.
