Launch of the latest maintenance free inline refractive index sensor. An entry-level device at attractive entry-level pricing.


We are pleased to announce a new member of the Anton Paar inline refractometer family.

The L-Rix 4100 Transmitter is the entry model of the optical inline refractometer series. Once immersed in the process liquid, it determines the concentration in °Brix derived from the refractive index and temperature.

Concentration and temperature are transmitted to external devices via 2 configurable 4-20 mA outputs, while the integrated HMI displays concentration and temperature, and offers additional configuration options.

Industry-leading optics, combined with a long-life LED, ensures that this unit is maintenance-free.
