This pocket-sized scale is ultra sensitive, weighing very fine amounts in increments of .1gram (.005oz) making it ideal for the diabetic, the body-builder, the nutritionist, or someone with special dietary needs. Powered by a lithium battery (included), the maximum it weighs is 250 grams or 8 ounces - perfect for small ingredients and portions. This scale is perfect for travel since it is compact enough to fit into a pocket or briefcase. When not in use, the food weighing tray inverts as a travel cover. The scale features an easy-to-read digital display, add and weigh facility, auto zero, and auto shut off. It comes with replaceable lithium batteries and a 10-year warranty.
