Timemore Black Mirror Duo Dual-Sensor Professional Coffee Brewing Scale

The Timemore Black Mirror Duo Dual-Sensor Professional Coffee Brewing Scale is part of Timemore’s advanced coffee scale range, designed for brewers who want more than simple weight and time measurement. Built for competitions, professional coffee bars, serious home brewing, and recipe development, the Duo allows users to measure both the water being poured into the brew bed and the final brewed coffee collected in the cup or server. This makes it especially valuable for brewers who want to understand not just how much water they pour, but how much beverage they actually extract.

What makes the Black Mirror Duo special is its dual-sensor weighing system. Most coffee scales only measure one weight at a time, usually the total brew weight on top of the scale. The Duo is different because it can track two key points in the brewing process: input at the brew bed and output in the final cup. This allows users to monitor brewing ratio, beverage yield, bypass, retention, and extraction behaviour with far more detail. For competition brewers and professionals, this helps create better repeatability, more accurate recipe tracking, and a clearer understanding of how each brew is performing.

The scale is highly sensitive, with 0.1g precision and a maximum capacity of 2kg, making it suitable for delicate manual brewing, competition-style pour-over, and controlled coffee testing. It is especially useful when brewing with drippers, servers, and cups where every gram matters. By showing both time and weight clearly, the Duo helps brewers refine pouring speed, total water input, final beverage weight, and extraction consistency. This makes it a powerful tool for dialing in recipes, comparing coffees, training baristas, and improving brew accuracy.

The Black Mirror Duo also features a minimalist touch panel design, clear LCD display, detachable adjustable drip stand, Bluetooth connectivity, and support through the Timemore app on iOS and Android. Brewing data can be displayed and recorded, making it easier to track recipes and repeat successful brews. Powered by a rechargeable 2300mAh battery with USB-C charging, it is practical for daily use in both home and professional environments.

To care for the Timemore Black Mirror Duo, wipe the surface gently with a soft damp cloth after use and dry it fully before storing. Avoid rinsing or submerging the scale, and keep water away from the charging port and internal electronics. Clean the drip stand separately when needed, and make sure all parts are dry before reassembling. Store the scale in a dry place away from excessive heat, moisture, and heavy impact to maintain weighing accuracy and long-term performance.
