DiFluid R2 Extract Refractometer

The DiFluid R2 Extract Refractometer is a high-precision digital tool designed for coffee professionals and enthusiasts who want to measure extraction with scientific accuracy. It measures Total Dissolved Solids (TDS) in real time, indicating the percentage of a beverage’s weight that comes from dissolved coffee material. Compact and portable, measuring coffee concentration with R2 Extract, CoffeeOS can help you determine your extraction yield to dial in your brew in a way that brings out the exact flavour profile you desire.

When paired with the DiFluid ecosystem and CoffeeOS app, the R2 Extract becomes part of a powerful brewing analysis system. It syncs seamlessly with compatible DiFluid scales to automatically calculate extraction yield, combining brew weight and TDS data for a complete overview of each cup. With fast readings, easy calibration, and lab-grade accuracy, it is an essential tool for cafés, roasters, and home baristas looking to refine flavour, improve consistency, and take full control of their brewing process.
