A checkweigher is a machine that serves as an automated scale, and weighs packaged products to ensure they are the correct weight. Checkweighers are commonly used in food manufacturing towards the end of the production process to check for products that are either underweight or overweight. Many checkweighers have automatic reject mechanisms that can remove underweight or overweight products from the production line without the need for an operator or for production to stop.
