DiFluid - R2 Extract - Coffee TDS Refractometer A precision coffee measurement tool designed for baristas, roasters, and dedicated home brewers who want to quantify and improve brew quality. The R2 Extract lets you accurately measure Total Dissolved Solids (TDS) - the key metric that reflects coffee strength and extraction. Key Features Instant TDS Measurement: Quickly determines the concentration of dissolved solids in brewed coffee to help you assess extraction and flavor balance. Bluetooth + CoffeeOS Integration: Syncs with the free CoffeeOS app to automatically calculate extraction and log brews on the Brew Control Chart for repeatable results over time. Easy Calibration: Effortless calibration with distilled or brew water for accurate and comparable readings. Durable Design: A larger sensor and modern optical system reduce the impact of external light — more durable and user-friendly than traditional refractometers. Home & Pro Use: Suitable for filter and espresso brews, giving you clear feedback to refine recipes and dialing in consistency. *SHIPS FROM SEY House ON APRIL 8, 2026
