Scales Catalog

A scale (usually just weighing scale) is a measuring instrument for determining the weight or mass of an object. A spring scale measures weight by the distance a spring deflects under its load. A balance scale compares the unknown weight to a standard weight using a horizontal lever. Weighing scale is used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight. Specialized bady scale and bathroom scale are used to measure the body weight of human beings.
