VAISALA POLARIS
Polaris™ PR53GC Compact Process Refractometer
The Vaisala Polaris PR53GC general-purpose compact process refractometer is designed for measuring concentrations of acids, alkaline solutions, alcohols, hydrocarbons, solvents, and various other solutions.
It can be installed directly in a pipeline and is suitable for production, transport, and quality-control applications in the chemical and other industries. Compact in size with over 500 different concentration curves, the PR53GC is suitable for a wide range of industrial applications.
- Reliable optical concentration measurements with refractive index
- Sulfuric acid, sodium hydroxide, and more than 500 concentration curves
- Special alloy materials available for demanding environments
- Type L coupling
- Measurement not affected by bubbles, particles, suspended solids, or color
- Various flow cells available
- Indigo520-compatible
- Built-in 4–20 mA and Modbus RTU outputs
- The optical measurement is based on the refractive index (RI).
- The RI can be measured from practically any liquid or slurry, and it responds to dissolved material.
- Bubbles, particles, or fibers in the process do not affect measurement.
- 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.
