The Earl Nano Smart Coffee Scale is a pocket-sized scale that does the maths for you. Measuring just 90 x 95 mm and 16 mm tall, it slips onto a drip tray or into a travel kit, then tracks time, weight, flow and brew ratio automatically so you can focus on the coffee.
Hands-free espresso shots
In Smart Espresso Mode, place your cup and the Nano tares itself. The timer starts as soon as coffee begins to flow and stops when extraction ends, locking your shot time and yield on screen. Brief pauses of up to 10 seconds are handled without losing the shot.
Pour-over with automatic brew ratio
Smart Hand-drip Mode records your dose, then starts timing the moment you pour. Water weight accumulates through blooms and multi-stage pours, and once you lift the dripper away the Nano locks the result and cycles between total time, total water, coffee weight and your coffee-to-water ratio.
See your flow at a glance
A light bar beneath the display expands from the centre as you pour or pull a shot, giving an instant visual read on flow rate without needing to watch numbers.
Precise and practical
Weighs in 0.1 g increments up to 2 kg, in grams or ounces. Auto wake switches the scale on and tares when around 50 g is placed on it, and it remembers your last mode and unit every time you power up.
Quiet when you need it
A three-position slide switch lets you choose power off, on with sound, or on in silent mode for early mornings.
Charge and go
The built-in 850 mAh lithium battery recharges via USB-C, and auto-off after five minutes of inactivity saves power between brews.
Ready to brew out of the box
Supplied with a silicone mat to protect the platform and a bean tray for weighing your dose.
Frequently Asked Questions
Does the Earl Nano Smart Coffee Scale have an espresso mode with auto timer?
Yes. The Earl Nano Smart Coffee Scale's Smart Espresso Mode tares automatically when you place your cup, starts the timer when coffee begins to flow and stops when extraction ends. Pauses of 10 seconds or less are treated as part of the same shot, and the final time and weight are locked on screen for about 10 seconds.
Does the Earl Nano Smart Coffee Scale calculate brew ratio for pour-over?
Yes. In Smart Hand-drip Mode, the Earl Nano Smart Coffee Scale records your coffee dose, tracks water weight as you pour and calculates your coffee-to-water ratio once brewing is complete. The result display cycles between time, total water, ratio and coffee weight for around one minute.
Will the Earl Nano Smart Coffee Scale fit on an espresso machine drip tray?
In most cases, yes. The Earl Nano Smart Coffee Scale measures 90 x 95 mm and 16 mm tall, small enough for most home espresso machine drip trays. Check your cup clearance under the spouts, allowing for the scale's height plus the silicone mat.
How accurate is the Earl Nano Smart Coffee Scale for weighing coffee?
The Earl Nano Smart Coffee Scale reads in 0.1 g increments with a maximum capacity of 2 kg, which suits espresso doses, shot yields and full pour-over brews. Use it on a stable, level surface and avoid weighing while charging for the most consistent readings.
How do I switch modes on the Earl Nano Smart Coffee Scale?
Double press the left (timer) button to switch between Manual, Smart Hand-drip and Smart Espresso modes on the Earl Nano Smart Coffee Scale. Double press the right button to switch between grams and ounces. The scale remembers your last mode and unit when you power it back on.
Can the Earl Nano Smart Coffee Scale be used silently?
Yes. The Earl Nano Smart Coffee Scale has a three-position slide switch for power off, power on with sound, and power on in silent mode, so you can brew without beeps.
How is the Earl Nano Smart Coffee Scale charged and how long does it stay on?
The Earl Nano Smart Coffee Scale has a built-in 850 mAh lithium battery that charges via USB-C. Use a standard adaptor rather than a fast charger. It powers off automatically after five minutes of inactivity and wakes again when around 50 g is placed on it.
Earl Nano Smart Coffee Scale vs Timemore Black Mirror Mini: which is better?
Choose the Earl Nano Smart Coffee Scale for the smallest footprint and automatic brew ratio. At 90 x 95 mm it is smaller than the Black Mirror Mini's 100 x 114 mm, and it adds a bean tray, ratio calculation and a silent mode switch. The Timemore Black Mirror Mini offers IPX3 splash resistance and a numeric flow rate readout. Both weigh up to 2 kg in 0.1 g increments.
