Collection: DiFluid

Why Choose DiFluid?

DiFluid builds precision coffee instruments that bring lab‑grade measurement into daily brewing and roasting, without the usual complexity or price barrier. From the DiFluid R2 Extract coffee TDS refractometer to the DiFluid Microbalance precision scale and the DiFluid Omni roast and particle analyzer, the brand focuses on one promise: turn intuition into data that is easy to understand and act on. With tight TDS accuracy, real‑time flow‑rate measurement, and near‑infrared roast and particle analysis all connected through the DiFluid Café app, DiFluid gives home baristas, prosumers, and cafés the tools to measure what they taste and then improve it systematically. DiFluid sits naturally in the Coffee Plus ecosystem as the “measurement brain” behind your espresso machines, grinders, and brewers, helping you dial in faster and replicate great results more easily.

DiFluid Measurement & Analysis Range

DiFluid’s flagship for brewing analysis is the DiFluid R2 Extract coffee TDS refractometer, a compact handheld device that measures total dissolved solids in brewed coffee with a range from 0–30% TDS, precision around ±0.02% and resolution down to 0.01%. In practice, that means you can measure the strength of your espresso, pour‑over, AeroPress or batch brew and then use extraction theory to understand whether you are under‑extracting, over‑extracting, or hitting the sweet spot. The R2’s aluminum sample dish offers roughly 675% better thermal conductivity than plastic, allowing it to reach temperature stability quickly and giving more reliable readings even when working with hot espresso shots. A bright color LCD makes results easy to read, and IP67 water resistance means you can simply rinse the sample dish under a tap, dry it, and move to the next shot without stress.

Complementing the R2 is the DiFluid Microbalance, a precision smart coffee scale designed for both espresso and pour‑over. The Microbalance offers 0.1 g resolution from 0.2 g up to around 1000 g (and 1 g resolution to 2000–3000 g depending on model), with extremely stable measurements that keep the readout from jumping while you brew. Auto‑detect timing means the timer starts the moment you begin pouring, which eliminates the common “forgot to hit start” problem and keeps recipes consistent. A real‑time flow‑rate display shows how fast water is entering your bed, helping you maintain steady pour‑overs and controlled espresso yield, while DiFluid Café app connectivity lets you log weight, time, and flow curves and review them later. For Coffee Plus customers using high‑end grinders and espresso machines, this scale is the missing link between careful preparation and reproducible results.

At the top end of DiFluid’s range sits the DiFluid Omni, a compact professional device that combines roast‑degree analysis with grind‑size distribution measurement in a single unit. Using two‑dimensional near‑infrared imaging, Omni measures the roast degree of whole beans or ground coffee while avoiding interference from background noise and silver skin, giving a more accurate picture of color than simple point‑type color meters. The same device then measures particle size distribution of ground coffee using an automatic vibration feeder that dispenses grounds without needing manual shaking, and presents uniformity metrics and distribution graphs on an HD touchscreen. For roasteries and advanced cafés, this lets you ask deeper questions: does a new grind setting really tighten distribution, does a new roasting profile change roast evenness, and how do these changes correlate with your sensory impressions and TDS readings?

Revolutionary Technologies / Innovation

DiFluid’s R2 Extract refractometer brings several key innovations to the coffee world. Its ±0.02% TDS precision and ±0.03% TDS accuracy rival far more expensive instruments, yet it fits in the palm of your hand and is rugged enough for daily café use. The aluminum sample dish dramatically improves heat transfer relative to plastic or low‑grade metal, which helps the device compensate for temperature variations more accurately and stabilize readings quickly even with hot espresso shots. An onboard microcalibration layer and advanced temperature compensation algorithms further refine readings, making R2 an appealing alternative to high‑end refractometers at a fraction of the cost.

The Microbalance and Microbalance Ti scales showcase DiFluid’s Intelligent Brewing System: software‑enhanced weighing that tracks time, weight, and flow‑rate simultaneously, auto‑starts the timer when you begin pouring, and communicates with the DiFluid Café app or CoffeeOS for real‑time graphing and analysis. Firmware can be updated over the air, meaning algorithm improvements and new features arrive via the app rather than requiring hardware upgrades. This “software‑defined scale” concept is relatively new in coffee; it means your scale actually gets better over time.

The Omni’s near‑infrared enhancement technology and automatic vibration particle feeder are perhaps DiFluid’s boldest innovations. Instead of measuring roast or grind at a single point, Omni uses two‑dimensional NIR imaging to read roast degree across a wider area, improving reliability by avoiding localized anomalies, then uses a smart vibration system to distribute grounds evenly for particle analysis without human bias. Data from Omni, R2, and Microbalance can all be linked through the DiFluid Café app, giving a unified view of roast degree, particle distribution, extraction strength, and brew curves for any given coffee—a powerful toolkit for roasters and cafés who want to truly understand cause and effect.

DiFluid Heritage / Innovation Legacy

DiFluid is part of the new wave of coffee‑tech companies born from the overlap of consumer electronics, data science, and specialty coffee. Rather than starting as a traditional machine manufacturer, DiFluid began from a measurement and instrumentation perspective, asking how to make lab‑grade analysis more affordable, more portable, and more integrated into everyday brewing and roasting workflows. The first‑generation DiFluid refractometers proved that a small, relatively inexpensive device could compete in accuracy with established premium brands, sparking adoption among baristas, roasters, and content creators who valued data‑driven brewing but previously found refractometers cost‑prohibitive.

Subsequent products expanded the ecosystem: Microbalance scales with app‑driven brewing, Omni analyzers that link roast and grind metrics with extraction, and continuous firmware and app updates that reflect feedback from professional users. This rapid iterative development, combined with close engagement with the global coffee community, has allowed DiFluid to evolve from “interesting gadget maker” into a serious instrumentation partner for roasters and cafés worldwide. For Coffee Plus, DiFluid represents the accessible, modern end of coffee analytics—tools that match how today’s Indian home baristas and small roasteries actually work.

Why DiFluid Stands Out

Unlike most coffee accessory brands, DiFluid does not produce brewers or machines; it focuses purely on measurement and data. This singular focus allows DiFluid to deliver tools like the R2 and Omni that are as relevant to high‑end roasteries and QC labs as they are to passionate home baristas. Where competitors often offer either basic kitchen scales or very expensive lab instruments, DiFluid occupies the middle: equipment engineered for coffee with serious precision and connectivity at prices reachable for individual baristas, micro‑roasters, and cafés.

The DiFluid Café app and CoffeeOS integration also set the brand apart. Instead of leaving each device as a standalone tool, DiFluid connects refractometer readings, brew curves, and roast/particle data into a unified interface where recipes can be saved, compared, and shared. For Coffee Plus customers used to tracking espresso recipes, brew ratios, and roast dates, this integrated data environment feels natural—it turns subjective impressions (“this feels hollow” or “this shot is too heavy”) into quantifiable metrics that can guide recipe changes systematically.

Who DiFluid Is Perfect For

DiFluid is perfect for home baristas and prosumers in India who already care deeply about brewing and want to move from intuition to evidence‑based improvement. A DiFluid R2 refractometer and Microbalance scale let these users measure TDS and brew curves, test how grind adjustments affect extraction, and build repeatable recipes for their favorite Coffee Plus beans. For someone already controlling grind, dose, and water temperature, DiFluid becomes the next logical upgrade: a way to check whether “great tasting” shots are also sitting in optimal extraction ranges, or whether they can be improved further.

For specialty cafés and roaster‑cafés, DiFluid tools serve as practical quality‑control devices. A café can use R2 to spot‑check espresso strength across shifts, ensuring all baristas are hitting the same extraction targets, or to refine pour‑over recipes for new coffees. Microbalance scales on bar add real‑time flow‑rate feedback during V60 or Kalita brews, training baristas to maintain consistent pours. Roasteries and small production labs benefit from Omni’s roast‑color and particle‑distribution data, helping them tighten consistency across batches and better understand the impact of grind changes on extraction behavior.

DiFluid is also ideal for educators, consultants, and content creators who teach coffee brewing or roasting. Having portable, relatively affordable tools that measure TDS, roast degree, and grind distribution allows these professionals to demonstrate concepts in real time—showing students how changes in grind size or pour pattern translate into extraction percentage and flavor, turning abstract theory into tangible, data‑backed insights.

Technical Excellence and Quality Assurance

DiFluid devices are built around robust electronics, high‑precision sensors, and enclosures designed for real‑world coffee environments. The R2 refractometer’s IP67 water‑resistant design allows it to be rinsed under running water without damage, while the aluminum sample dish and advanced temperature compensation (microcalibration layer) ensure stable readings even as sample temperatures vary. TDS range from 0–30%, with precision around ±0.02% and resolution at 0.01% TDS, is more than sufficient for espresso, filter, and immersion brewing applications.

The Microbalance series scales provide 0.1 g resolution, stable readings with vibration filtration, and max capacities around 2000–3000 g depending on model, with automatic calibration and operating temperature windows tailored to typical indoor brew environments. Omni’s near‑infrared imaging system, automatic vibration feeder, and smart sampling algorithms are designed for repeatable measurement of both beans and grounds, with HD touchscreen displays and Bluetooth connectivity that support both standalone use and app integration. Firmware and app‑based updates ensure that DiFluid products stay current with evolving best practices and user feedback, extending functional lifespan beyond static hardware specifications.
