Acaia Lunar Espresso Scale - Professional Barista Scale with Flow-Rate Indicator & Auto-Brew Modes

Precision espresso extraction requires real-time data, the Acaia Lunar delivers it with the speed, accuracy, and water-resistant durability that commercial espresso environments demand. Redesigned with enhanced responsiveness and intuitive flow-rate monitoring, this scale transforms espresso preparation from timing guesswork into measured, repeatable control.

Real-Time Flow Monitoring

The integrated Flow-Rate Indicator provides live visual feedback during extraction, allowing you to observe when flow accelerates, plateaus, or begins channeling. This immediate data enables mid-shot adjustments and builds the pattern recognition necessary for diagnosing extraction issues and achieving shot-to-shot consistency—particularly critical when dialing in new coffees or adapting to ambient humidity changes.

Commercial-Grade Construction

Water-resistant anodized aluminum housing protects Acaia's industrial weighing technology from the steam, splashes, and temperature fluctuations inherent to espresso bar service. The compact footprint fits directly onto drip trays across commercial espresso machines, while the fast response time captures weight changes in real-time without the lag that renders standard scales ineffective for monitoring extraction.

Customizable Workflow Integration

Programmable auto-start modes eliminate manual timer activation, while the Tare Save function stores your preferred portafilter or dosing cup weight for instant zeroing. These automation features streamline high-volume service while maintaining the precision measurement that specialty coffee preparation requires. Full parameter customization through the companion app allows fine-tuning display brightness, auto-off timing, and measurement units to match your specific workflow.

Professional Support & Accessories

Includes heat-resistant pad and 100g calibration weight for immediate use. Two-year manufacturer warranty covers water damage, reflecting the scale's design for daily commercial espresso service. Optional accessories (sold separately) include the Lunar Weighing Plate for expanded surface area, Lunar Base for elevated positioning, and Lunar Carrying Case for transport between locations.

Selected for its flow-rate monitoring capability, commercial durability, and the measurement precision that specialty espresso extraction demands.
