DIFLUID R2 Extract
Designed for Precision Coffee Brewing
Unlock the full potential of every brew with the DIFLUID R2 Extract, a coffee refractometer engineered specifically for coffee professionals and enthusiasts. It accurately measures Total Dissolved Solids (TDS%), showing the concentration of dissolved coffee compounds in your finished beverage.
When paired with CoffeeOS, the R2 Extract automatically calculates extraction yield, giving you the insights needed to fine-tune recipes and consistently achieve your desired flavor profile—from balanced sweetness to bright acidity and rich body.
Modern Sensor Technology
Old
Unlike traditional CCD-based refractometers that require extremely precise alignment, the R2 Extract utilizes modern CMOS sensor technology for improved durability and dependable performance.
New
The larger light-sensitive surface of the CMOS sensor is more tolerant of slight movement or alignment variations, allowing it to capture measurement data more efficiently while maintaining excellent accuracy during everyday use.
Maintaining Accuracy with Microcalibrations
Every measurement is automatically fine-tuned using a built-in reference standard that performs micro-calibrations before each reading. This process compensates for even the smallest variations, ensuring reliable and repeatable results every time.
An aluminum sample dish rapidly distributes heat across the coffee sample, minimizing temperature fluctuations that could affect measurement accuracy.
