Features
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.
