{"product_id":"difluid-omni-roast-color-meter-particle-size-analyzer","title":"DiFluid Omni Roast Color Meter and Particle Size Analyzer","description":"\u003cp class=\"product-lead\"\u003eThe 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.\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. Compatible sieve stacks connect directly to the Omni for structured sieve analysis.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNear-infrared imaging:\u003c\/strong\u003e multiple NIR wavelengths penetrate beneath the bean surface for sub-surface color capture\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull distribution output:\u003c\/strong\u003e returns color and particle distributions across the whole sample, not a single averaged point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoast metrics calculated automatically:\u003c\/strong\u003e Roast Delta, Peak Shift, and Uniformity computed from each measurement\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParticle size analysis:\u003c\/strong\u003e 100–2500 µm range, 1 µm resolution, with auto-dispersion for consistent sample prep\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandalone or connected:\u003c\/strong\u003e 2.8-inch IPS touch screen for standalone use; CoffeeOS app for in-depth analysis and data logging\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete sample kit included:\u003c\/strong\u003e sample prep base, particle base, bean\/grounds dish, roast calibration plate, scraper, bean scoop, brush, USB-C cable, and carrying box\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\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eColor Range\u003c\/td\u003e\n      \u003ctd\u003e0–150 Agtron\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eColor Precision\u003c\/td\u003e\n      \u003ctd\u003e±0.1 Agtron\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eColor Resolution\u003c\/td\u003e\n      \u003ctd\u003e0.1 Agtron\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eParticle Range\u003c\/td\u003e\n      \u003ctd\u003e100–2500 µm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eParticle Resolution\u003c\/td\u003e\n      \u003ctd\u003e1 µm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eScreen\u003c\/td\u003e\n      \u003ctd\u003e2.8-inch IPS touch screen\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBattery\u003c\/td\u003e\n      \u003ctd\u003e2500 mAh\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCharge Input\u003c\/td\u003e\n      \u003ctd\u003e5V 1A (USB-C)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (Main Unit)\u003c\/td\u003e\n      \u003ctd\u003e109 × 79 × 72 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (Main Unit)\u003c\/td\u003e\n      \u003ctd\u003e290 g\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIncluded Accessories\u003c\/td\u003e\n      \u003ctd\u003eSample prep base, particle base, bean\/grounds dish, roast calibration plate, scraper, bean scoop, brush, USB-C charging cable, carrying box\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 Omni suits specialty roasters, quality-control labs, and serious home roasters who need repeatable, distribution-level data on roast color and grind particle size.

Sieve stacks are compatible accessories but are not included in this listing.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the Omni require a phone or computer to operate?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat color standard does the Omni use, and how accurate is it?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe 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.\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.
