The Office of Weights and Measures is responsible for ensuring that all commercial and law enforcement weighing and measuring devices are tested and inspected for accuracy, and meet federal guidelines for specifications and tolerances.  The Office of Weights and Measures is a division of the Passaic County Department of Health Services.  

As a unit of the Division of Consumer Affairs, Weights and Measures officials work to keep the marketplace honest by using highly accurate equipment to inspect scales, meters, scanning equipment, gasoline station pumps, and lumberyards throughout the State.  Weighing or measuring devices are not permitted to be used for commercial purposes unless they have been registered with the Office of Weights and Measures.
