Digital Scale, 2000 g x 0.1 g This new digital scale will meet all your home science needs! It is easier and faster to use than a mechanical balance, which greatly reduces your preparation and lab time. This scale has a very large 2000g capacity with a 0.1g sensitivity. It is ideal for most junior high and high school science courses, including chemistry. It features a 5" diameter pan, large high-contrast display, backlight, automatic tare feature, keypad calibration, and hinged protective cover. It weighs in grams, ounces, troy-ounces, and pennyweight. It includes four AA batteries and calibration weights. Five-year warranty from Home Science Tools. Grades ,1202, $49.95 We recommend this digital scale as a faster, easier-to-use, and more economical alternative to a traditional mechanical balance. It will work for all labs in this curriculum.
