Omix Plus
Know the density | moisture | water activity | screen size | roast color before you commit the lot.
Omix Plus measures moisture, water activity, density, screen size, bean volume, sample weight for all coffee stages, plus roast color distribution for both whole bean and ground coffee. Import and visualize results in CoffeeOS.
Water activity ±0.005 Aw · Moisture ±0.1 % · Density ±0.5 g/L · Roast color ±0.1 Agtron · Bean volume ±20 mm³

Measurement
What you get from one test.
Fill a container, put the main unit on top, press the button. Tap any reading to see what it measures and what to do with it.
Worth knowing
Menglian Badu, China, natural Catimor, received 12 July, roasted on a Roest L200 Ultra in 4:12.
Color Distribution
What does an average leave out?
Switch between the three views and see how they differ.
Roast A and Roast B are an illustration, built to average identically. The whole bean and grounds figures are from the Menglian Badu session.

Water activity
0.584Aw
Ranges: METER Group, Maintaining Green Coffee Quality Through Water Activity Control, and Sustainable Harvest’s 2016–2020 storage study, reported in Daily Coffee News. Growth limits: How Water Activity Controls Microbial Growth. Ochratoxin A on green coffee: Pardo, Marín, Ramos & Sanchis, Journal of Food Protection 68(1):133–138, 2005.
Moisture is how much water is in the bean. Water activity is how much of that water is free to move. Only the second one predicts how a lot ages.
Omix Plus measures water activity by chilled-mirror dew point, the reference method rather than a resistance probe estimation, to ±0.005 Aw in as little as 30 seconds.
So a delivery can be checked as it arrives, and checked again in month four to see what your warehouse is doing to it. Two lots can arrive at the same moisture and hold that water differently, and six months on they will not be in the same condition.
Storage guidance, not a specification. Set your own limits and hold them.

In the box
What comes in the case.
Everything you need to get going.
Container A. Green coffee, parchment and dried cherry, about 150 g. Moisture, density, screen size, bean volume, weight and water activity all come from this one.
Container B. Roasted whole beans, about 18 g. Color only.
Container C. Ground coffee, about 5 g. Color only.
Container D. Agtron calibration reference.
Scraper and brush. Leveling is the largest source of drift in density and color. Draw the scraper across the rim so the sample sits as level as possible with the top edge, and do not press it down.
Sample base, toolbox, tempered-glass film, USB-C cable. The main unit and the sample base carry separate batteries and charge together while they are attached.
Calibration solution bottle. Water activity calibrates against a saturated salt solution you make and pour into container B.
Omix Plus
Green coffee and roasted coffee, measured on the same bench, filed under the same bean.
