Key specs for this scale
Precision: 0.1g
This accuracy level allows you to measure small changes in coffee dose or water weight. You get consistent extraction because even slight variations affect flavor. This precision is standard for serious home brewing. It helps you dial in ratios for espresso or pour-over. Compare this to scales that only measure in whole grams, which offer less control over your brew strength.
Weight Capacity: 3kg
The scale can hold up to three kilograms of weight. This high limit lets you weigh large carafes or multiple cups at once. You can brew for a group without exceeding the maximum. This capacity is useful for batch brewing or heavy commercial setups. It ensures the device remains stable under heavy loads. Check this limit if you often weigh large vessels filled with water.
Display Type: dual-zone LED
The screen shows two pieces of information at the same time. You can see weight and time simultaneously without switching modes. This clarity helps you monitor flow rates during pour-over. The LED interface is easy to read in various lighting conditions. It reduces the need to guess or look away from your pour. Compare this to single-value displays that require manual toggling between functions.

The Auto Timer for Pour-Over mode helps you manage flow rates. The Auto Timer for Espresso mode tracks extraction time. The Standard Weighing mode works for any method. You set your coffee-to-water ratio between 1:1 and 1:18. The scale calculates the target water weight for you. An audible beep signals when you reach your target. This removes the need to watch the timer and the scale at the same time. The real-time flow rate indicator updates as you pour. This helps you adjust your technique for consistent results.

Before you buy this scale
You should verify that your brewing vessels fit within the 3kg capacity and the physical footprint of the device. The listing notes a compact size, but you must ensure your preferred dripper, such as a V60 or Chemex, sits securely on the platform. Since the display is IPX4 water-resistant, you can rinse it easily, but you should avoid submerging the unit. The silicone pad protects against heat, so keep it clean to maintain grip. You will need a USB-C cable for charging, which the listing confirms supports up to 90 days of use. This scale complements any grinder by adding precise timing and weight control. It fits well alongside other gear in Coffee Grinders & Coffee Gear by focusing on the water side of the equation. Check that your counter space accommodates the dual-zone LED interface for clear visibility. The device operates independently without an app, so you rely solely on its built-in controls. Ensure your power source is accessible for the occasional recharge.
Check before you buy
