​Weights and Measures Inspections

The Wisconsin Department of Agriculture, Trade and Consumer Protection's Bureau of Weights and Measures is responsible for regularly monitoring the accuracy of gas pumps, price scanners, scales and package weights statewide to ensure that consumers are receiving their money's worth in Wisconsin stores.

In addition to monitoring accuracies at Wisconsin stores, Weights and Measures inspectors are also responsible for testing fuel quality and fuel pump safety at fueling facilities statewide.

Some municipalities in Wisconsin maintain their own weights and measures program. Cities administering their own program employ their own inspectors; however, city inspectors enforce the same laws and standards as state inspectors. A list of municipalities with their own weights and measures program can be found here.

The Bureau of Weights and Measures compiles an annual statistics. The results are available here.
