Acaia Umbra Duo Scale

The Acaia Umbra Duo is a larger, display-free precision scale with a double-sized platform, built for demanding brew bar workflows. It leverages the same industrial-grade weighing tech as the Umbra line but expands capacity and flexibility, while sharing real-time data via Magic Relay.

Who It’s For & Why You Need It

  • Commercial baristas & high-volume cafés:
    Need: a scale that can handle large dosing or simultaneous brewing.
    Why Duo: its elongated 210 mm pan gives space for a portafilter and cup, or two cappuccino cups side-by-side — perfect for splitting shots or dual brews. 

  • Home baristas dialing in bigger yields:
    Need: more capacity than a compact scale but don’t want a bulky footprint.
    Why Duo: supports up to 1,500 g, compared to the original Umbra’s 1,000 g.

  • Multi-scale setups:
    Need: clean, efficient workflows with minimal screen clutter.
    Why Duo: via Magic Relay, it shares a display with another Acaia scale (like a Pearl or Lunar), so you can always see weight changes without adding another readout. 

  • Minimalists focused on energy efficiency:
    Need: long battery life and low power draw.
    Why Duo: display-free design + efficient electronics yields 40–48 hours of active use, with up to 14 days on standby.

Why It Stands Out

  • The Duo adds expanded real estate without compromising the lean, display-free design of the Umbra line — ideal for baristas who need both capacity and a clean workflow.

  • It retains Acaia’s high-precision ReacX weighing technology, matching the Umbra’s sensitivity and repeatability.

  • Its Magic Relay function ensures seamless display sharing: place weight on either scale and the paired display updates instantly — no delay or workaround. 

  • Built for industrial / café environments, the Duo’s aluminum body is durable, while the energy-efficient design means it's less likely to run out mid-shift.
