Inline Process Refractometers
Hygienic inline refractometry for continuous measurement of refractive index, °Brix and concentration directly in production liquids. Explore L-Rix 5100 configurations, technical characteristics and Tetra Pak Part Number references for accurate component identification.
Refractive index and concentration measurement directly in the process
The L-Rix 5100 is an optical hygienic inline refractometer intended for determination of refractive index (RI) in liquids. The instrument can be immersed directly in the production liquid and continuously displays °Brix and concentration values.
Inline refractometry provides continuous process information without the need to rely solely on intermittent laboratory sampling. The appropriate configuration depends on the required communication interface, display arrangement and Product Selection functionality.

Identifying the correct L-Rix 5100 configuration
Do not select the instrument from the L-Rix 5100 model name alone. The complete communication and operating configuration should be confirmed before ordering.
Identify the Interface
Confirm whether the installed instrument uses Profinet, Ethernet IP or analog output.
Check Display Configuration
Determine whether the required version is without display or equipped with a local display.
Confirm Product Selection
For relevant versions, confirm whether Product Selection functionality is required and verify the corresponding Tetra Pak Part Number.
