- 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.
