Frequently Asked Questions
Is there a difference between the black and white Omni besides color?
Nope! Buy one of each and you can mix and match the bases 😉
What is the sample size?
Between 15 and 17 grams for whole bean, and 3-5 grams for whole grounds, depending on density and moisture content.
How do you calibrate?
Particle size is calibrated at the factory and is fixed, so it does not need to be calibrated.
Roast color is calibrated using a standard color card. For greater accuracy, it is recommended to purchase a ColorGuard dual color plate for more precise calibration.
