Acaia's Lunar espresso scale is the toast of the coffee industry. Compact enough to fit on any espresso machine's drip tray, the Lunar sports a water-resistant anodized aluminum frame that is extremely durable. It features a built-in timer combined with auto-timing and auto-tare modes, accuracy down to 0.1g, Bluetooth connectivity, 30 hour battery life, and a real-time flow rate indicator—allowing you to geek out on your coffee data completely.
