Vaisala Polaris™ PR53GP and GPEX Probe Process Refractometers for ordinary and explosive areas
Measure concentrations of sugars/Brix, acids, alkaline solutions, alcohols, hydrocarbons, solvents, and various other solutions directly in pipelines and tanks, in production transport and perform quality control in sugar, chemical, petrochemical, and other industries.
The Vaisala Polaris PR53GP probe process refractometer is the concentration measurement solution of choice for sugar, chemical, petrochemical, and other industries. Optional cooling cover is available for processes where extreme temperature is common.
Typical applications include crystallizers, wet scrubbers, reactors, transport pipelines, and blending and distillation operations.
Built for sugar industry
The Vaisala Polaris PR53GP process refractometer is best suited measurement device for the sugar crystallization process when paired with the Zutora SeedMaster-4, as well as in various steps when processing sugar crops to crystals and other products.
The PR53GP is built for sugar industry inside out. On the inside, our special image detection algorithm for sugar crystallization enables accurate mother liquor concentration measurements during crystallization strike and especially when the crystals form. On the outside, the design is built to resist high heat, both ambient and process. Full measurement range covers 0 -100 Brix, which makes the product ideal for sugar manufacturing. Vaisala’s product comes with bolted flange refractometer options for highest operator safety. A special partner network is ready to serve you, including commission and start-up.
Maximum productivity and safety in hazardous areas
The industry-leading Vaisala Polaris process refractometers offer Ex-certified product versions for hazardous areas.
Depending on selected product option, the refractometers are designed to be installed in either
IECEx/ATEX Zone 0/1 (North America Class 1 Division 1) or Zone 2 (Class 1 Div 2).
The Polaris Ex-versions are Indigo520 compatible to secure maximum productivity.
The Indigo520, and the associated IS equipment in case of Zone 0/Class 1 Div 1, is placed in the safe area.

Always accurate, no drift
The measurement is based on optical measurement of the refractive index (RI). The RI can be measured from practically any liquid or slurry, and it is sensitive to dissolved material. Bubbles, particles or color do not affect the measurement.
Plug & play to Indigo
The process refractometers can be connected to Vaisala Indigo520 transmitter to expand features, including data storage, graphical interface, analog and digital interface.
Easy mounting
The Vaisala Polaris™ PR53GP can be installed in standard flanges making it easy to mount to process line, and with the optional cooling cover accessory, the instrument tolerates high process pressure and high process temperatures. Optional flange mounted pipe flow cell installation accessory allows flange mounted installation to wide variety pipe sizes.
