A checkweigher for the in-motion weighing of objects being transported along a conveyor line. A checkweigher of the present invention employs a plurality of scales each having its own set of weighing conveyor elements. For example, a first scale may be associated with a set of lighter weight chains to convey and weigh smaller objects, while a second scale may be associated with a set of heavier weight chains to convey and weigh larger objects. This design essentially allows the incorporation of a lightweight and heavyweight checkweigher within one common checkweigher frame.
