Who it fits

Key specs explained for this scale

Weight Capacity: 3000g (3kg)

This capacity allows you to weigh large batches of beans or full carafes of brewed coffee. Most espresso scales cap at 2kg, so this extra room helps if you weigh multiple shots or large pour-over volumes in one session. It ensures you never exceed the limit when measuring heavier ingredients for baking or large brews, making it versatile for both coffee and kitchen tasks.

Precision: 0.1g

A 0.1g graduation means the scale detects tiny changes in weight. This level of detail is essential for espresso, where small dose variations affect extraction. You can adjust your grind or dose with confidence. For pour-over, it helps maintain consistent ratios. This precision is higher than standard kitchen scales, which often read only to 1g, giving you better control over your brew strength.

Built-In Timer: Timer with Automatic Espresso Mode

The integrated timer tracks extraction time alongside weight. The automatic espresso mode likely starts timing when weight change is detected, simplifying your workflow. You do not need a separate stopwatch. This helps you dial in shots by correlating time and weight. It is useful for comparing different beans or grind settings, ensuring consistency in your daily brewing routine without manual intervention.

Display Type: LED

The LED display provides bright, clear numbers for easy reading. This is helpful in low-light kitchen environments or when looking down at a small surface. White text on a dark background typically offers good contrast. You can quickly read your dose and time without straining your eyes. This visibility ensures you do not miss small weight changes during critical moments of your brewing process.

Design, Build, and Layout

The listing states the scale measures 1 by 1 by 1 inches. This compact footprint allows it to sit on small counters or near espresso machines without taking up much room. The unit weighs 1.18 pounds. This light weight makes it easy to move or store when not in use. The listing describes the finish as black. A dark color helps hide fingerprints and minor spills during daily use.

The controls are touch-sensitive. You can activate the tare function and timer with a simple tap. The listing mentions sound feedback for every touch, which you can mute.

This means you do not need to buy disposable batteries. You can charge the device using a standard cable. The listing highlights a two-year warranty for manufacturing defects. This covers the build quality and internal components according to the seller.

This removes the need for frequent battery replacements and keeps your workflow consistent. Once charged, the scale is ready for immediate use. The interface relies on a bright LED display with white text. You can read these numbers clearly in low light or bright kitchen environments.

If you prefer quiet mornings, you can mute these sounds easily. The scale measures 1 by 1 by 1 inches.

This setup requires no app or complex pairing. It works independently as a dedicated tool for your coffee bar.

Before You Buy This Scale

You need to check if your espresso machine fits under the platform. The listing notes a one-by-one-by-one-inch footprint, but does not specify the maximum cup height clearance. You should measure your portafilter and group head to ensure it clears the display and buttons. Since the device uses a USB-C port, you must have a compatible cable. The listing mentions a removable silicone mat, which helps protect surfaces from heat and spills. You should clean this mat regularly to maintain accuracy and hygiene. This scale sits alongside other gear in your setup. Its high precision suits detailed espresso work, while the 3kg capacity handles larger brews.

This tool complements your workflow rather than replacing other essential equipment.

Check before you buy
