Dial in every brew.
The OutIn Claro is a compact coffee scale made for espresso and pour over, at home or on the road. It reads to 0.1 g across a range of 0.3 g to 2000 g, so it handles everything from a single dose of beans to a full pour over with the server on top. The round, low profile body slides under the OutIn Nano, a portafilter, or a dripper without fighting for space.
Three modes do the thinking for you. Standard is a plain scale with timer. Espresso (M1) auto tares your cup, starts timing when the first drops land, and pauses when the flow stops. Pour Over (M2) remembers your coffee dose and shows water weight live so you can hit your ratio without a calculator. One side switch covers power, mode, and mute.
The included food grade silicone mat shields the scale from heat and spills, and the hard case keeps it safe in a bag.

Overview
Overview
Precision that travels.
The OutIn Claro is a compact round coffee scale designed to sit neatly under a cup, a dripper, or a portable espresso machine. It reads to 0.1 g, so your doses and yields stay consistent wherever you brew.
Three smart modes, Manual, Espresso, and Pour-Over, tare automatically and calculate your coffee to water ratio for you. A side switch turns it on, off, or mutes it, and a food-grade silicone mat protects it from heat and splashes. It also works well for weighing matcha when you want every bowl to taste the same.
One charge lasts around 400 brewing cycles, and it ships with a waterproof, scratch-resistant protective case for travel.
How to use
How to use
- Power on: use the side switch to turn the scale on.
- Pick a mode: choose Manual, Espresso, or Pour-Over.
- Place and tare: set your cup or brewer on the silicone mat. Smart modes tare automatically.

💡 Tip: For espresso, a 1:2 ratio (18 g in, 36 g out) is a great starting point.
