Vaisala Polaris™ PR53GP Probe Process Refractometer
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.
Best suited for petrochemicals production
Eliminate sampling, improve product consistency and optimize your processes. Easier than ever. The Vaisala Polaris PR53GC Process Refractometer measures inline and feeds the results to control systems. It helps improve operator safety and frees them to focus on other important tasks.
