The new robust platform of inline process refractometers adds to Vaisala’s leading-edge innovations by introducing the first fully inhouse developed refractometer series to product platform that combines both liquid and gas measurement capabilities.

Vaisala, a global leader in weather, environmental, and industrial measurements continue to strengthen its spearheading industrial product ecosystem by unveiling a next-generation process refractometer platform PolarisTM. The products are designed to optimize industrial manufacturing processes, product quality, enhance productivity, and save resources, energy, and time in various industries and hundreds of industrial applications.

Unique product platform for liquid measurement needs in industrial processes

With the launch of its Polaris Process Refractometer product family Vaisala offers the most modern product platform for liquid measurement needs that brings together Vaisala’s over 85 years of measurement excellence with the latest liquid measurements expertise.

“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,” comments Product Manager Jarkko Ruonala from Vaisala.

The launched refractometer platform continues also to strengthen Vaisala’s modular Indigo measurement ecosystem.

Ruonala says: “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, real-time. Processes include evaporation, distillation, fermentation, blending, filtration, crystallization, interface detection, dilution, extraction and more. 

Vaisala Polaris™ PR53AC Process Refractometer and Vaisala Polaris™ PR53AP Process Refractometer are 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.

Vaisala Polaris™ PR53GP Process Refractometer is 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.

In pulp & 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.

Vaisala Polaris™ PR53W Process Refractometer measures sulphuric acid, hydrochloric acid (HCI), sodium hydroxide, and other aggressive chemicals directly inline in the chemical, metal, and mining industries.

Vaisala Polaris™ PR53M Process Refractometer helps chemical and semiconductor industries in measuring hydrochloric acid (HCI), sodium hydroxide, sodium chloride, sulphuric acid, and other aggressive chemicals directly inline.

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.

The Polaris product range will be globally available during 2023.
