The Ozeri Rev Digital Kitchen Scale with Electro-Mechanical Weight Dial is the world's first digital kitchen scale to incorporate a synchronized electro-mechanical dial and LCD that automatically illuminate and display the measured weight both digitally and mechanically. Boasting a visually arresting design, the Ozeri Rev Digital Kitchen Scale is equipped with 4 new high-precision sensors that accurately weigh from 0.1 oz to 11 lbs (5000 g) in graduations of 0.1 oz or 1 gram. With its dual display system, the Ozeri Rev Kitchen Scale provides a digital display for precision measurements in ounces, grams or millimeters, and a mechanical analog dial for viewing measurements of heavier items in both lbs and kg simultaneously. The Rev utilizes a Touch Tare button to instantly calculate the net weight of your ingredients, and a convenient Unit button to change the unit of measurement displayed on the LCD from lbs:oz to grams and ml. The Rev runs on 3 AAA batteries (included) and features a low battery indicator. Your satisfaction is 100 percent guaranteed.
