A checkweigher is an automatic machine for checking the weight of packaged commodities.  Checkweighers are normally used on line in the production floor and its main purpose to ensure that the weight of a pack is within specified limits. Any packs that are outside the tolerance are taken out of line automatically. This is not only required by law, but also beneficial for manufacturers to help them reach greater efficiency at lower costs.

The right application of weight control techniques can allow the food production and packaging manufacturer to virtually eliminate consumer complaints about underweight packages. Well-crafted and maintained checkweigher systems can also help the manufacturer significantly reduce costs related to overweight packages by decreasing the average fill weight through improved accuracy. 

Checkweighers can be integrated with metal detectors, x-ray machines, bar-code scanners etc. An industrial motion checkweigher can sort products from a fraction of a gram to many, many kilograms. 

Various type of rejectors are available as per requirement like Pusher, Arm, Stop Belt, Flap, Drop Belt, Up Belt etc.
