Checkweighers are used to ensure correct product weight before final packaging or shipping. Often, the installation of a checkweigher provides profit benefits to the user by controlling filler or scale accuracy to minimize product giveaway. Checkweighers are also used to assure compliance with label weight regulations and to eliminate consumer complaints associated with missing items or low-weight packaging conditions.

These systems weights 100% of the products for the ultimate quality control as instead of sample based controls, each and every product is evaluated. These versatile scales are often equipped with rejection systems or diverters, designed to move the product away from being further processed.
