Fiber optic refractive index sensor FRI

1、 Introduction to Fiber Refractive Index Sensor FRI:
FRI fiber optic refractive index sensors are used to measure refractive index and continuously monitor various processes (such as food processing and chemical processes), eliminating the difficulties of manual sampling and measurement repeatability. FRI sensing trend can be adjusted to zero in the air, and can be used for micro official shells or solid stainless steel pipe shells, suitable for industrial applications. Completely free from electromagnetic and radio frequency interference, it has inherent safety for chemical environments. Essentially safe, FRI refractometers are easy to clean and can be placed hundreds of meters away from electronic devices, ensuring the safety of the sampling process.

2、 Characteristics of Fiber Optic Refractive Index Sensor FRI:
1) Range: 1.0000 to 1.7000 RI
2) Accuracy: ± 0.0005 RI
3) Resolution: 0.0001 RI
