DiFluid Brew Control System Ti Coffee Brewing Bundle

The DiFluid Brew Control System Ti pairs the Microbalance Ti brewing scale with the R2 Extract TDS refractometer in a single bundle, giving home brewers and serious coffee enthusiasts a complete, data-driven workflow for dialing in extraction. 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.

Measure What Actually Matters

The 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.

Track Every Pour in Real Time

The 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.

One App Ties the Workflow Together

CoffeeOS 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.

Features

• R2 Extract TDS refractometer: measures brewed coffee concentration from 0–30% TDS with ±0.03% accuracy and a 4-second test time
• Microbalance Ti brewing scale: 3,000 g maximum capacity with live flow rate display, countdown timer, and vibration filtration
• CMOS sensor with microcalibration: each R2 Extract reading self-calibrates against a reference material for consistent accuracy across sessions
• IP67 water resistance (R2 Extract): rinse the sample dish under tap water for fast cleanup
• CoffeeOS integration: both instruments sync to the app for recipe building, brew recording, extraction analysis, and brew control charting
• High-capacity battery (Microbalance Ti): 2,500 mAh; R2 Extract carries a 430 mAh battery, charges via USB-C at 5V 0.3A

Specifications

Who This Is For and Isn't

The 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.

This 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. Buyers who need only a standalone scale or only a refractometer may find the individual instruments better matched to their needs.

Common Questions

What does TDS actually tell me about my coffee?

TDS, or Total Dissolved Solids, is the percentage of a brewed coffee's weight that comes from dissolved coffee material. 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.

How does the Microbalance Ti differ from the standard Microbalance?

The 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.

Do both instruments need to be connected to a phone to use them?

The 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.

Is the R2 Extract difficult to keep clean?

The 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.

Does this bundle include roast color or particle size analysis?

No. 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.

What is the R2 Extract's measurement accuracy, and how does it maintain it?

The 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. The CMOS sensor used in the R2 Extract has a larger light-sensitive area than older CCD-based designs, which reduces the accuracy loss that can result from minor misalignment during normal use.
