Refractometer Excellence R4
Accurate, Intuitive, and Modular. The all-rounder for daily routines: The Excellence R4 refractometer offers fast refractive index measurements in the range from 1.32 to 1.70, with automatic temperature control from 0 to 100°C.
Simple One Click™ Operation
The One Click™ user interface enables users to start a complete workflow with one click including sampling, measuring, rinsing, drying, and SOPs.
The user management system allows for different level of access to be defined, with each user having their own personalized home screen and language.
Measurement limits can be set for color-coded pass/fail information for accepted and rejected samples.

Automatic Temperature Control
The integrated Peltier temperature control quickly heats up or cools down the measurement cell, maintaining the sample reliably at the desired temperature.
The status light of the instrument shows if it is ready for a measurement (green), busy (blinking), or waiting for operator action (orange).
Automated Sampling, Rinsing and Drying
Automating workflows saves time, reduces costs and improves safety. The R4 is compatible with a large portfolio of autosamplers including solutions for single or multiple samples, and samples which are solid at room temperature.
The Excellence R4 can be upgraded to a dedicated automatic multi-parameter system combining density, refractive index, pH, color, titration and more to save time, increase data quality and prevent any alteration of samples between individual analyses.
