TIMEMORE
Two sensors, one clearer picture of your brew
One sensor in the base plate measures total water poured; a second in the dripper stand measures drawdown weight in your server. Comparing the two shows exactly how much of your pour actually made it through the coffee bed.
TIMEMORE
Starts timing the moment you pour
Auto-timing kicks in as soon as water hits the scale, so there's no button to hit mid-pour. The hidden LED display stays invisible until touched, keeping the matte black surface clean and uncluttered.
TIMEMORE
A stand that moves where you need it
The dripper stand adjusts in height and slides side to side, and detaches fully when you just need a single-sensor scale. It fits your own dripper of choice — V60, Kalita or otherwise — which isn't included.
TIMEMORE
Built for a full session, not just one pour
A 1600mAh battery charges over USB-C and is rated for roughly 240 brews per charge, with auto-off to save power between uses. The weighing surface is water-resistant, though the charging port isn't.

Frequently asked questions
What's the difference between the two sensors?
The base plate sensor measures the total water you pour, while the stand sensor measures the drawdown weight reaching your server. Comparing the two shows how much of your pour actually extracted through the coffee bed.
Does the Black Mirror DUO connect to an app?
No. This is Timemore's upgraded Black Mirror V2 tech built deliberately without Bluetooth or app connectivity, keeping the scale simple to pick up and use straight away.
How long does the battery last?
The 1600mAh battery is rated for roughly 240 brews, or around 20 hours of use, per charge. An auto-off function helps preserve battery between sessions, and it recharges over USB-C.
Can I use it with any pour-over brewer?
Yes — the adjustable stand fits most standard drippers, including V60 and Kalita styles. Note that the dripper itself isn't included; the DUO is designed to work with the brewer you already own.
What's included in the box?
The scale, the adjustable dripper stand, a silicone heat mat, a USB-C charging cable and an instruction manual. A dripper or brewer isn't included — the stand is designed to hold the one you already have.

The Black Mirror DUO is built specifically for pour-over brewers who want to understand what's actually happening in the cup, not just what went into it. The second sensor on the dripper stand is the whole point — comparing water poured to coffee extracted gives you real data on drawdown, without needing an app or a subscription to get it. Built on Timemore's upgraded Black Mirror V2 tech, deliberately without Bluetooth.
