Portafilter Weighing Plate for Acaia Lunar by acaia, model AA007

The Portafilter Weighing Plate for Acaia Lunar is a purpose-made accessory that fits on the Acaia Lunar scale to support a portafilter during espresso dosing and extraction measurement. Designed by acaia, the plate provides a stable, low-profile surface that aligns with the Lunar platform so the scale can register weight changes accurately while preparing shots. It is intended for use with typical commercial and home-style portafilters and helps streamline repeatable dosing and shot monitoring.

Advantages

The weighing plate delivers a firm, slip-resistant contact area that reduces movement of the portafilter and improves measurement consistency. Its low profile minimizes interference with the scale sensor and allows the portafilter to sit naturally in place. The plate is constructed to be easy to attach and remove, enabling rapid transitions between dosing and tare operations. By providing a dedicated surface for the portafilter, it reduces the need for third-party adapters and preserves the accuracy of the Acaia Lunar scale during routine use.

Suitable for

• Baristas dosing ground coffee directly into a portafilter on the Acaia Lunar scale
• Measuring extracted espresso weight for shot analysis and consistency
• Home or professional espresso setups that require portable and repeatable dosing workflow

Key specifications

• Compatibility: designed specifically to integrate with the Acaia Lunar scale platform
• Function: supports portafilters for dosing and extraction weight measurement
• Profile: low-profile design to reduce interference with scale sensors
• Material characteristics: durable, stable surface suitable for repeated use (material finish may vary)
• Mounting: easy to attach and remove for quick workflow changes

How to use

Place the weighing plate on the Acaia Lunar platform so it sits flush with the scale surface. Position the portafilter on the plate and tare the scale to zero if dosing grounds, or start the measurement when extraction begins to record shot weight. During dosing or extraction, avoid side loading the portafilter and ensure it remains centered on the plate for accurate readings. After use, lift the plate off the scale for cleaning and storage.

Usage recommendations

For best results, confirm the plate is correctly seated on the Lunar platform before each use, keep the contact surface clean and free of coffee debris, and tare the scale with the portafilter in place when measuring dose weight. Avoid excessive lateral force on the portafilter while weighing to maintain accuracy and prolong the service life of both the plate and the scale.
