    Key Details:

    Description

    Två påsar från samma ursprung kan se identiska ut men bete sig helt olika i rostningen. Fuktighet och densitet varierar mellan batcher och dessa faktorer påverkar direkt hur värmen rör sig genom bönan, hur snabbt utvecklingen sker och hur förlåtande ett kaffe är.

    CoffMeter M1 mäter båda på under två sekunder. Det är ett praktiskt, exakt verktyg byggt för rosterier som vill ha mer konsekvens utan komplexiteten eller kostnaden för analysutrustning i kommersiell klass.

    Fuktighet och densitet på under två sekunder

    Lägg i ditt prov och M1 ger nästan omedelbart en fuktighetsavläsning med ±0,2 % noggrannhet och en densitetsavläsning med ±1 g/L. Det är tillräckligt exakt för att meningsfullt jämföra partier, följa förändringar i grönt kaffe över tid och göra välgrundade justeringar av din rostprofil innan du börjar.

    What Can You Actually Do With This Information?

    Moisture content affects how a coffee responds to heat. Higher moisture means slower drying, more energy required, greater risk of tipping or scorching if you don't adjust. Density tells you how hard or easy the bean structure is to break down - denser beans generally need more time and energy to develop fully. Knowing both before you roast means you're dialling in with data, not guesswork.

    Works Across the Whole Supply Chain

    The M1 isn't just useful at the roasting stage. It supports green beans, roasted beans, parchment, and dried cherries - so it's equally useful when evaluating new lots at intake, checking stored coffee for moisture drift, or tracking how a roast has developed post-drum.

    Built for Regular Use

    A 2500mAh battery gives you up to 10 hours of continuous use, charging fully in four hours via USB-C. It connects to DiFluid's CoffeeOS app via Bluetooth to log and track readings over time. Calibration is handled at home using the included standardised material - no lab required. Replacement calibration material will need to be purchased periodically.

      The build quality is excellent — it has a nice heft to it and the metal housing feels like anodized aluminum. Nothing about it feels cheap. I calibrated it straight out of the box and tested around ten different beans from various origins. The readings have all fallen within a range that seems reasonable. I re-tested two samples after recalibration and the results barely moved - Blue Moon read 11.1% then 11.0%, a red honey read 9.3% then 9.2%. That kind of consistency is reassuring.

      Made by the same people who make DiFluid, which has become something of an industry standard for colour and moisture testing. This is their lower cost product for small roasters and hobbyists - and it shows what they can do at a more accessible price point.

    Vanliga frågor

    How much coffee do I need for a reading?

    Around 150g of green coffee, depending on density. The M1 uses a volumetric chamber, so denser beans will weigh slightly more for the same volume.

    Does the M1 measure water activity?

    No - it measures moisture percentage and density. Water activity is a different measurement that tells you about microbial safety and long-term storage stability. If that's something you need, take a look at the CoffMeter W1.

    What's the difference between the M1 and DiFluid's Omix?

    The Omix measures the same things but adds water activity, roast colour, bean volume, and environmental conditions. It's built for more intensive use and is priced accordingly. The M1 gives you the two most actionable data points for home roasting at a significantly lower cost.

    Does calibration expire?

    The included calibration material has a limited shelf life. When it expires, replacement material needs to be purchased separately from DiFluid. Calibration itself is straightforward and done at home.

    What's in the box?

    CoffMeter M1, bean sweeper, USB-C cable, calibration material, carry case.
