Compare Coffee Scales - Side-by-Side Specs

Refresh rate (Hz) is how often the scale updates the displayed weight per second. A 2Hz scale updates twice per second—too slow to track pour-over flow in real time. A 60Hz scale updates 60 times per second, giving instant feedback as you pour. For pour-over, 60Hz enables flow rate tracking; 10Hz is acceptable for basic use. Budget scales rarely advertise refresh rate—assume 1-2Hz. The Timemore Black Mirror and Acacia Pearl are the main 60Hz options under $200.

Yes—a built-in timer is essential for coffee. Brew time (e.g., 3:00-3:30 for pour-over) affects extraction. Having weight and time on one device simplifies workflow. All recommended coffee scales include timers. Some scales start the timer automatically when weight increases; others require manual start. Either works—consistency matters more than the specific implementation.

Rechargeable scales (Acacia, Fellow, Timemore) typically last 20-40 hours of use per charge—weeks of daily brewing. AAA battery scales (Hario, Greater Goods) last months to a year depending on use. CR2032 coin cell scales (Weightman) have shorter life—replace every few months. Rechargeable is more convenient long-term; battery models are fine for occasional use or travel.
