The Microbalance Ti handles up to 3,000 g and tracks live flow rate and pour timing; the R2 Extract measures brewed coffee concentration in TDS% with ±0.03% accuracy. Both instruments connect to the CoffeeOS app, where recipe building, brew recording, and extraction analysis happen in one place.\u003c\/p\u003e\n\n\u003ch2\u003eMeasure What Actually Matters\u003c\/h2\u003e\n\u003cp\u003eThe R2 Extract refractometer measures Total Dissolved Solids (the percentage of a brewed coffee's weight that comes from dissolved coffee material) and reports it as TDS%. That single number tells you whether a brew is under-extracted, over-extracted, or dialed in, and CoffeeOS uses it to calculate extraction yield so you can trace a flavor result back to a specific recipe variable. The R2 Extract reads in four seconds, is rated IP67 for easy rinsing, and uses a CMOS sensor with a larger light-sensitive area than older CCD designs, which means minor handling shifts or misalignment have less effect on accuracy. Each reading also runs a microcalibration against a reference material, and the aluminum sample dish spreads heat evenly across the sample to keep temperatures stable between tests.\u003c\/p\u003e\n\n\u003ch2\u003eTrack Every Pour in Real Time\u003c\/h2\u003e\n\u003cp\u003eThe Microbalance Ti supports up to 3,000 g, providing headroom for larger brew vessels, full carafes, or espresso setups, and displays live flow rate alongside elapsed time so you can match pour speed to your target without watching a phone screen. Vibration filtration keeps the reading stable on surfaces that aren't perfectly level. A 2,500 mAh battery is built in, and the scale connects directly to CoffeeOS's Brew Recorder, which marks pouring stages automatically from the recorded data. From that recording, CoffeeOS can generate a repeatable recipe that captures bloom time, pour intervals, wait time, agitation, and all the variables that are easy to forget between sessions.\u003c\/p\u003e\n\n\u003ch2\u003eOne App Ties the Workflow Together\u003c\/h2\u003e\n\u003cp\u003eCoffeeOS is the shared platform for both instruments. The Brew Controller plots your extraction data on a brew control chart so you can see where a cup lands relative to your preferred flavor zone and understand what to adjust next. The Brew Recorder converts a live brew session into a structured recipe, including grinder setting, brewer type, water temperature, and brew time, that you can follow exactly on the next attempt. If you also use the DiFluid Omni color and particle analyzer, roast color and grind evenness data auto-fill into the same recipe record, though the Omni is sold separately and is not included in this bundle.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR2 Extract TDS refractometer:\u003c\/strong\u003e measures brewed coffee concentration from 0–30% TDS with ±0.03% accuracy and a 4-second test time\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicrobalance Ti brewing scale:\u003c\/strong\u003e 3,000 g maximum capacity with live flow rate display, countdown timer, and vibration filtration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCMOS sensor with microcalibration:\u003c\/strong\u003e each R2 Extract reading self-calibrates against a reference material for consistent accuracy across sessions\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP67 water resistance (R2 Extract):\u003c\/strong\u003e rinse the sample dish under tap water for fast cleanup\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoffeeOS integration:\u003c\/strong\u003e both instruments sync to the app for recipe building, brew recording, extraction analysis, and brew control charting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-capacity battery (Microbalance Ti):\u003c\/strong\u003e 2,500 mAh; R2 Extract carries a 430 mAh battery, charges via USB-C at 5V 0.3A\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eR2 Extract\u003c\/th\u003e\n      \u003cth\u003eMicrobalance Ti\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasurement range\u003c\/td\u003e\n      \u003ctd\u003e0–30% TDS \/ RI 1.33299–1.38660\u003c\/td\u003e\n      \u003ctd\u003e3,000 g max\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAccuracy\u003c\/td\u003e\n      \u003ctd\u003e±0.03% TDS \/ RI ±0.00004\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePrecision\u003c\/td\u003e\n      \u003ctd\u003e±0.02% TDS\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eResolution\u003c\/td\u003e\n      \u003ctd\u003e0.01% TDS \/ RI 0.00002\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTest time\u003c\/td\u003e\n      \u003ctd\u003e4 seconds\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating temperature\u003c\/td\u003e\n      \u003ctd\u003e5°C–40°C\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBattery\u003c\/td\u003e\n      \u003ctd\u003e430 mAh\u003c\/td\u003e\n      \u003ctd\u003e2,500 mAh\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCharging\u003c\/td\u003e\n      \u003ctd\u003eUSB-C, 5V 0.3A\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWater resistance\u003c\/td\u003e\n      \u003ctd\u003eIP67\u003c\/td\u003e\n      \u003ctd\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpecial features\u003c\/td\u003e\n      \u003ctd\u003eCMOS sensor, microcalibration, aluminum sample dish\u003c\/td\u003e\n      \u003ctd\u003eFlow rate display, countdown timer, vibration filtration\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eApp compatibility\u003c\/td\u003e\n      \u003ctd\u003eCoffeeOS (iOS and Android)\u003c\/td\u003e\n      \u003ctd\u003eCoffeeOS (iOS and Android)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWhat's included\u003c\/td\u003e\n      \u003ctd colspan=\"2\"\u003eR2 Extract refractometer, Microbalance Ti scale\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Brew Control System Ti suits home brewers and prosumers who want to move beyond intuition and build genuinely repeatable recipes, particularly those brewing pour-over, batch brew, or espresso at volumes up to 3,000 g and who want extraction data (TDS%, yield) to guide adjustments rather than relying on taste alone. The CoffeeOS platform rewards users who brew regularly and want to track variables across sessions.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis bundle does not include roast color analysis or particle size measurement; those capabilities require the DiFluid Omni, which is sold separately. The bundle also does not include any physical grinder tool; it measures brewed liquid and weight only.

The R2 Extract refractometer measures this in seconds, and CoffeeOS uses the TDS reading alongside your brew ratio to calculate extraction yield: the share of the coffee grounds that actually dissolved into the cup. Together, those two numbers tell you whether a brew is under-extracted, over-extracted, or in your target range, and point toward which variable to adjust next.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eHow does the Microbalance Ti differ from the standard Microbalance?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Microbalance Ti included in this bundle supports a 3,000 g maximum capacity and carries a 2,500 mAh battery. The standard Microbalance is a separate product with a 2,000 g maximum and a 1,000 mAh battery. Both connect to CoffeeOS and share the same flow rate, timer, and recipe features, but the Ti's higher capacity and larger battery make it better suited to larger brew vessels and longer sessions.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDo both instruments need to be connected to a phone to use them?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Microbalance Ti displays time and live flow rate on its own screen without a phone. The R2 Extract delivers a TDS reading on its own display in four seconds. CoffeeOS is required to access recipe building, brew recording, extraction analysis, and the brew control chart, as those features depend on the app, but basic measurements from each instrument work standalone.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs the R2 Extract difficult to keep clean?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe R2 Extract carries an IP67 water-resistance rating, so the sample dish can be rinsed under tap water and wiped dry after each use. Avoid fully submerging the device, particularly around the charging port; routine dish rinsing is straightforward. The aluminum sample dish is designed to spread heat evenly, which also helps prevent residue from affecting subsequent readings.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes this bundle include roast color or particle size analysis?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The Brew Control System Ti includes only the Microbalance Ti scale and the R2 Extract refractometer. Roast color analysis and particle size measurement are features of the DiFluid Omni, which is a separate instrument sold individually. CoffeeOS does support Omni data within the same recipe workflow if you add one later, but the Omni is not part of this bundle.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the R2 Extract's measurement accuracy, and how does it maintain it?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe R2 Extract measures TDS with ±0.03% accuracy and ±0.02% precision. Each test runs a microcalibration against a reference material before reporting a result, correcting for small variations in conditions or handling.

Using multiple near-infrared wavelengths and a modern CMOS imaging sensor, the Omni captures a full color and particle size distribution across an entire sample, giving roasters and grinders a detailed picture of roast level and grind consistency rather than one averaged number. It operates as a standalone unit via its built-in 2.8-inch IPS touch screen, or connects to the CoffeeOS app for deeper analysis.\u003c\/p\u003e\n\n\u003ch2\u003eDistribution Over Averages\u003c\/h2\u003e\n\u003cp\u003eMost color meters return a single Agtron number. The Omni measures across the entire sample and returns a distribution, so a batch with a wide spread of roast levels reads differently from a uniform one even when both average to the same number. That distinction matters when diagnosing roast consistency, adjusting drum load, or comparing two roast profiles side by side. The Omni also calculates Roast Delta, Peak Shift, and Uniformity automatically, turning raw color data into actionable roast diagnostics.\u003c\/p\u003e\n\n\u003ch2\u003eWhole Bean and Ground, Side by Side\u003c\/h2\u003e\n\u003cp\u003eThe Omni measures both whole bean and ground coffee, and its software visualizes the difference between the two readings in the same session. Because the near-infrared sensor penetrates beneath the bean surface, it captures color information that visible-light meters miss, giving a more complete picture of how heat has developed through the bean rather than just at its surface.\u003c\/p\u003e\n\n\u003ch2\u003eParticle Size Analysis in the Same Instrument\u003c\/h2\u003e\n\u003cp\u003eBeyond roast color, the Omni includes a particle size analysis mode with a particle range of 100 to 2500 µm and a resolution of 1 µm. An auto-dispersion mechanism spreads the sample before imaging, reducing clumping that would otherwise skew the distribution. Grinders can use this to verify grind consistency, compare burr sets, or document the particle profile of a specific recipe.

Color precision is ±0.1 Agtron and resolution is 0.1 Agtron, making it suitable for quality-control work where small roast-level differences need to be reliably distinguished.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eCan the Omni measure both whole beans and ground coffee?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The DiFluid Omni measures both whole bean and ground coffee samples. Its software can display both readings in the same session and visualize the difference between them, which is useful for understanding how roast development at the surface compares to the interior of the bean.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat particle size range does the Omni cover, and what accessories does it need?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe DiFluid Omni covers a particle size range of 100 to 2500 µm with a resolution of 1 µm. The particle base and bean\/grounds dish required for particle analysis are included in the box. Compatible sieve stacks can be connected for structured sieve analysis but are sold separately.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is included in the box?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe DiFluid Omni ships with the main unit, a sample prep base, a particle base, a bean\/grounds dish, a roast calibration plate, a scraper, a bean scoop, a brush, a USB-C charging cable, and a carrying box.
