Basic Operation
Sample Preparation
- put fine ground coffee into an espresso basket
- tamp hard
Scanning
- lift Tonino and put it on top of the coffee sample
- read the roast degree from the display
By tamping instead of just leveling the coffee the results are less influenced by the grind.
Features
- small sample size
- gesture-driven
- wireless operation and charging
- target mode
- user-defined scales
- environmentally friendly
- open-source Tonino app
(Mac/Windows/Linux)
