Vaisala Polaris PR53GP Probe General Purpose Process Refractometer

Vaisala K-PATENTS process refractometer series are based on 40 years of experience and continuous development. The PR53 family is the latest generation of digital process refractometers.

The Vaisala Polaris PR53GP general-purpose probe process refractometer is designed for measuring concentrations of sugars/Brix, acids, alkaline solutions, hydrocarbons, solvents, and various other solutions. It can be installed directly in a pipeline or tank and is suitable for production and quality-control applications in the sugar, chemical, petrochemical, and other
industries.

The optical measurement is based on the refractive index (RI). The RI can be measured from practically any liquid, and it responds to dissolved material. Because bubbles, particles, or crystals in the process do not affect measurement, the RI allows accurate measurement for different chemicals. Typical applications include crystallizers, wet scrubbers, reactors, transport pipelines, blending, and distillation operations. The outstanding long-term stability provides years of accurate, continuous, fast, and stable concentration measurement directly in the process stream. Inline process  refractometers are easy to install and have no moving parts that require regular maintenance.

Compatible with Indigo520 transmitter, which gives you access to features such as data storage, graphical interface, and analog and digital interface.
