DiFluid R2 Extract Refractometer
The DiFluid R2 Extract Refractometer is a precision digital tool designed for specialty coffee professionals and enthusiasts who demand accuracy in every brew. Measure extraction percentage instantly to achieve optimal taste, balance, and consistency in your espresso and filter coffee
How it works:
Place a single drop of cooled coffee on the optical surface. The R2 analyzes light refraction through a calibrated 2D CMOS sensor and dual temperature compensators, displaying extraction data within seconds. No guesswork—pure data-driven brewing.
Why extraction matters:
Under-extracted coffee tastes sour and thin. Over-extraction becomes bitter and harsh. The R2 reveals the exact extraction percentage, enabling you to dial in grind size, water temperature, and contact time with scientific precision.
Features:
Advanced 2D CMOS image sensor with micro-calibration layer ensures ±0.5% accuracy across temperature ranges. Dual temperature sensors compensate for sample variance. Sync with DiFluid Café app to log extractions, track trends, and correlate data with other DiFluid instruments for complete brew profiling.
Built for precision espresso measurement and filter coffee analysis.
Essential for baristas, roasters, and home enthusiasts pursuing café-quality consistency.
