The DiFluid Omni is a coffee measurement instrument for roasters and grinders who need more than a single-point reading. 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.
Most 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.
The 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.
Beyond 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. Compatible sieve stacks connect directly to the Omni for structured sieve analysis.

The Omni suits specialty roasters, quality-control labs, and serious home roasters who need repeatable, distribution-level data on roast color and grind particle size. It is equally useful for grinder comparison, burr characterization, and recipe documentation where a single averaged reading is not sufficient.
The Omni is not a brewing scale or TDS refractometer and does not measure extraction yield or brew strength. It is not suited to buyers who need only a basic single-point Agtron reading and have no use for distribution data or particle analysis. Sieve stacks are compatible accessories but are not included in this listing.
The DiFluid Omni operates as a fully standalone instrument using its built-in 2.8-inch IPS touch screen, so no phone or computer is required for basic color and particle measurements. Connecting to the CoffeeOS app unlocks deeper analysis, data logging, and additional visualization tools, but the app is optional.
The DiFluid Omni measures roast color on the Agtron scale, covering a range of 0 to 150 Agtron. 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.
Yes. 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.
The 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.
The 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. No sieve stacks are included.
