Acaia Lunar Coffee Scale
Acaia Pearl Model S Coffee Scale
Our take
The two scales match on 0.1 g resolution, timer, auto tare and flow-rate display, so the choice is about your bench. The Acaia Lunar Coffee Scale fits on an espresso drip tray, but its small platform is awkward for portafilters. The Acaia Pearl Model S Coffee Scale takes up to 3000 g. Pick the Lunar for a tight espresso setup, the Pearl Model S otherwise.
