Know before you buy
With dimensions of 4.1 x 4.1 x 0.6 inches, the Lunar is designed to fit comfortably on the drip trays of most professional and prosumer espresso machines. We recommend measuring your machine's clearance between the portafilter spouts and the drip tray to ensure you have enough room for both the scale and your cup.
The flow rate feature allows you to visualize the speed of your extraction in real-time. By monitoring this data, you can identify channeling or inconsistencies in your puck preparation, helping you make more informed adjustments to your grind size or tamping technique.
Yes, the Lunar is built with a durable, anodized aluminum body designed to withstand the humid and messy environment of an espresso station. While it is water-resistant, it should not be submerged in water; simply wipe it down with a damp cloth after use.
No, the scale functions perfectly as a standalone device for weighing and timing your shots. The Bluetooth connectivity and app integration are optional features intended for users who want to log their brewing data or customize advanced settings.
The rechargeable lithium-ion battery typically lasts between 30 to 40 hours of continuous use on a single charge. Since it uses a standard USB-C connection, it is easy to top off the battery during your regular maintenance routine.
Yes, the Lunar allows you to toggle between grams and ounces depending on your preference. You can easily adjust the unit of measurement through the scale's settings or via the connected mobile app.
