Refractive Index Cell RX4 - Overview - METTLER TOLEDO

Refractive Index Cell RX4

Accurate, Intuitive, and Modular. The RX4 Refractive Index Cell can be added to an Excellence Density meter to measure density and refractive index simultaneously. The RX4 measures the refractive index in the range from 1.32 to 1.70, with automatic temperature control from 0 to 100°C.

Seamless Modularity

The RX4 can be combined with the Excellence Density Meter to provide a space-saving system for measuring refractive index and density simultaneously.

Upgradable System

The system can combine more than just density and refractive index, it can also be flexibly upgraded to measure pH, color, titration and more.

Automatic Temperature Control

The integrated Peltier temperature control quickly heats up or cools down the measurement cell, reliably maintaining the sample at the desired temperature.
