Mechanical Counting scales are versatile weighing machines that can be used for counting and weighing objects simultaneously. Typical applications include checkweighing, for checking the weight of objects against a pre-set limit to performing accurate parts counting procedures to reduce manual counting.

Chicken Scales (or weigh scales or scales) are devices to measure weight. Spring balances or spring scales calculate weight that is the product of mass into gravity (9.807 m/s2) on the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of one or more known masses.
