{"product_id":"difluid-r2-extract-refractometer","title":"DiFluid R2 Extract Refractometer","description":"This compact digital refractometer delivers precise TDS and extraction readings for coffee professionals and enthusiasts. A calibrated 2D CMOS imaging sensor captures uniform samples and reduces alignment errors. Dual temperature sensors compensate for environmental variation to improve measurement consistency. The instrument measures a 0–30% TDS range with 0.01% resolution and ±0.02% precision to support both espresso and brewed coffee workflows. A high-resolution color display shows detailed readouts and selectable testing modes for rapid decision-making. The aluminum sample dish increases thermal conductivity to stabilize readings faster than standard glass dishes. A microcalibration layer and hydrophobic nano-coating reduce residual contamination and help preserve optical surfaces. IP67 water resistance allows simple rinsing of the sample dish and routine cleaning without special handling. Companion DiFluid Café app integration records, visualizes, and exports data for recipe development and quality tracking. Pocketable dimensions and a low-profile form make this unit suitable for busy baristas, QC labs, and home brewers. Rubber feet and a stable base reduce vibration and improve repeatability on crowded countertops. USB-C rechargeable power and an on-screen battery indicator simplify long shifts and frequent testing. Included accessories—sampling spoon, microfiber cloth, protective pouch, and USB-C cable—enable immediate setup and basic maintenance. Measurement requires minimal sample volume to limit wasted brew during frequent checks. Repeatable, accurate readings help inform extraction targets, grind adjustments, and recipe refinement. Robust aluminum and optical glass components balance portability with routine handling demands. A one-year limited manufacturer warranty covers typical professional and consumer use cases. Clear on-device menus paired with app-driven visualizations reduce operator training time. The design supports regular in-service calibration workflows and straightforward maintenance.\u003cbr\u003e\u003cbr\u003e\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eSample dish material\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eAluminum sample dish for improved thermal conductivity\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eOptical sensor\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eCalibrated 2D CMOS imaging sensor to reduce alignment errors\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eCoating \u0026amp; calibration\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eMicrocalibration layer and hydrophobic nano-scale coating on optical surface\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eTemperature sensors\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eDual temperature sensors for environmental compensation\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eMeasurement range \u0026amp; resolution\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e0–30% TDS range; 0.01% resolution; ±0.02% precision; ±0.03% accuracy\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eDisplay\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eHigh-resolution color display with multiple testing modes\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eWater resistance \u0026amp; cleaning\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eIP67 water resistant; sample dish can be rinsed and wiped dry\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003ePower \u0026amp; charging\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eUSB Type-C rechargeable battery (cable included)\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eDimensions (approx.)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003e12.0 × 6.0 × 3.0 cm\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n    \u003ctr\u003e\n      \u003ctd\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd\u003eRefractometer, USB-C cable, sampling spoon, microfiber cloth, protective pouch\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"DiFluid","offers":[{"title":"Default Title","offer_id":52859388690739,"sku":"DFT-RE2","price":300.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/6468\/5107\/files\/difluid-r2-extract-refractometer-9463128.jpg?v=1766265909","url":"https:\/\/uaicoffee.ca\/fr\/products\/difluid-r2-extract-refractometer","provider":"Uai Coffee","version":"1.0","type":"link"}
