Add to Wishlist
  • Designed for brewing espresso with consistent precision, the reimagined Lunar is fast, responsive, and accurate. This scale is built with water-resistant anodised aluminium and Acaia’s own leading industrial weighing technology. It is an essential element for any commercial environment and fits perfectly onto espresso machines.

    Brew your own way with customizable parameters, a choice of automated brewing modes, and a new Tare Save feature to save the weight of your preferred dosing container. The visual feedback provided by the new Flow-Rate Indicator will also help you monitor your extraction in real time, achieving more consistent shots and allowing you to adjust more accurately for perfect espresso extractions.

    Accessories that are sold separately include the Lunar Weighing Plate and Lunar Base. Each Lunar scale comes with a heat resistant pad and a 100 g calibration weight. The Lunar includes a 2-year limited manufacturer’s warranty, which also covers water damage.

    The Acaia Lunar Professional Espresso Scale, Redesigned
    Reintroducing the essential Lunar scale, now with brand new abilities and features! This includes our latest weighing technology, a faster response time, a built-in Flow-Rate Indicator, USB-C charging, and a brighter display for seamless daily use.

    The scale still has all the familiar features you love, including several auto-start modes, 0.1 g accuracy, and a rechargeable battery with more than 30 hours of life. See the new Lunar in action in this video.

    Fast, Sensitive, and Responsive
    With the latest weighing technology, the Lunar stabilises faster during brewing, saving you precious time and creating a smooth workflow.

    Real-Time Flow-Rate Indicator
    The new Flow-Rate Indicator allows you to monitor the flow rate of your shot in real time. This lets you spot the subtle changes in the extraction, understand your shot better, and make adjustments for a perfect espresso.

    Customisable Espresso Workflow Parameters
    Built-in espresso modes will automatically start and stop a timer or tare to speed up your preferred workflow. The new Tare Save function allows you to store the tare weight of your preferred dosing container or cup.

    USB Type-C Recharging
    A greener alternative power source, the lithium-ion battery can last up to 30-40 hours. In addition, we have upgraded the charging port to USB Type-C with PD Support, which contributes to longer battery life and protection.

    Highest Readability Up To 0.01g
    The Lunar offers a high readability option of 0.01 g, which gives you an extra digit of reference for the most accurate espresso weight.
