- PRECISE 0-30% TDS AT ±0.02% - 10X MORE ACCURATE THAN STANDARD MODELS. Most digital refractometers deliver ±0.2% accuracy, not enough to dial in an extraction. R2 Extract measures to ±0.02% precision with 0.01% resolution, so the difference between a 1.35% and 1.45% reading is real data, not instrument noise.
- CMOS SENSOR WITH PER-MEASUREMENT MICROCALIBRATION - Unlike CCD sensors that lose accuracy from minor misalignment, R2 Extract's CMOS sensor self-corrects before every reading. The aluminum sample dish equalizes temperature in 4 seconds, no warm-up, no drift, just consistent results.
- APP-CONNECTED FOR POUR OVER, ESPRESSO, AND SPECIALTY COFFEE - R2 Extract pairs with the CoffeeOS app to calculate extraction yield automatically, plot brews on the Brew Control Chart, and store recipes. Every measurement becomes a data point, so each cup builds on the last. Pairs with DiFluid Microbalance Ti for a complete brew-to-TDS ecosystem.
- IP67 WATERPROOF AND USB-C RECHARGEABLE - Rinse the sample dish directly under tap water between tests, no disassembly, no cross-contamination. IP67 handles real cafe conditions: splashes, steam, wet countertops. A 430mAh battery charges via USB-C and lasts through full service periods.
- FOR SPECIALTY COFFEE PROFESSIONALS AND HOME ENTHUSIASTS ALIKE - Trusted by baristas, roasters, and serious home brewers who need reproducible results. Compact at 88 x 36 x 16mm, fits an apron pocket. Backed by DiFluid's one-year warranty and per-unit quality checks.
