FISO | Refractive Index

Refractive index

Fiber optic refractive index sensors developed and manufactured by FISO are suitable for various applications such as quality control, research & development and in-line process control. When used as in-line refractometers, they allow continuous measurement of key characteristic of fluidic mixtures.


Widely used in cooling system industry to monitor the quality of oil in the carter of compressor to assess the reliability of compressors, they also find their place in the petrochemical industry.


With different designs and configurations, our products present the following characteristics:

  • Broad range of reading: 1.0 to 1.7 RI
