A checkweigher is an automatic or manual machine for checking the weight of packaged commodities. It is normally found at the offgoing end of a production process and is used to ensure that the weight of a pack of the commodity is within specified limits. Any packs that are outside the tolerance are taken out of line automatically.
A checkweigher is an automated system used in production lines to weigh products in motion (dynamically) to ensure they meet specified weight limits. It acts as a key quality control tool, typically rejecting items that are underweight or overweight.
