Easy to use, yet powerful and accurate, the DiFluid R2 Extract refractometer offers incredible precision, a variety of data display options, and advanced temperature compensation for a stable measurement. It’s also IP67 water resistant, making it easy to use and maintain.

Precision of ±0.02% with our most advanced refractometer.
Capable of displaying a variety of data for expanded testing options with its color display.
Aluminum sample dish provides 675% improved temperature conductivity for stable measurements.
IP67 water resistance allows for easy testing and rinsing.
Advanced temperature compensation through the use of a special Microcalibration layer.

R2 Extract’s bigger, higher-resolution color display allows for a greater density of information, for more testing modes, and greater versatility.

• Standard Test – press the button and water the results appear- simple
• Mulit-Test – Set a number of tests, and let R2 do the rest.  The result is an average
• Stable Test – Testing begins automatically when temperature change is detected.  Final results display when a stable temperature is reached.

The micro calibration layer compensates for external disturbances and physical deformations such as temperature changes or undissolved particles, greatly improving accuracy and stability.
