 Vaisala Polaris™ process refractometer is designed to measure and indicate inline liquid concentration of almost any chemical or compound.

The refractometer can be installed cost-efficiently in the main processing line, bypass line or vessel to control the raw and in-process materials in order to extract their maximum value and achieve high quality end products. The performance of all types of chemical refining, manufacturing, and quality-control operations can be dramatically improved with Vaisala’s refractive index measurement technology – whether they are in continuous or batch processes. 

Unlike intermittent sampling, continuous monitoring provides instant feedback on changes in the process, and this data can enable real-time and precise process control of the common chemical industry operations, e.g.:

• Reactor, reaction degree, and endpoint determination
• Evaporation
• Dissolving tank or vessel
• Dilution, mixing or blending
• Solid-liquid extraction
• Absorbers and wet scrubbers
• Ion exchangers
• Distillation
• Interface detection and product identification of product-to-product interfaces in loading/ unloading
• Quality control

Using the Vaisala concentration measurement technique and its easy integration into plant engineering systems enables significant improvements in the plant capacity, the process safety or product yields.
