The ZeroHero Mini Smart Coffee Scale is a compact digital scale for making both espresso and filter coffee. With a precision of 0.1 g, it helps you better control your coffee dose, the amount of water, and the resulting extraction ratio. It’s ideal for home baristas, travel, and small coffee corners, as it measures 13.5 × 12 cm and is 2.2 cm tall. It weighs 270 g and has a weighing range from 0.2 g to 2,000 g.
Smart modes for more convenient preparation
The espresso mode automatically activates when a load of 30 g or more is placed on the scale; it then performs a tare and starts the timer the moment the first drops hit the cup. For filter coffee, you’ll appreciate the ratio mode, which calculates the ratio of coffee to water in real time. This helps keep your recipe consistent without having to manually adjust the ratio during preparation.
Battery and Practical Design
The scale is powered by a rechargeable 1800 mAh battery, which lasts up to 18 hours of continuous use and more than 2 months in standby mode. It charges via USB-C. The body is made of silicone, ABS, and PC and is available in black. The scale is resistant to minor contact with water and also includes an insulating silicone pad that helps protect it from heat and minor spills.
Care and Recommendations
Do not submerge the scale in water, as it is an electronic device with sensitive internal sensors. Wipe it down after use and store it in a clean, level place. Do not leave heavy objects on the weighing surface for extended periods to avoid unnecessary strain on the sensors and to maintain the scale’s accuracy.
