Weights & Measures

The Bureau of Weights and Measures serves a valuable consumer and commercial protection function within the Illinois Department of Agriculture. The bureau's pursuit of equity in the marketplace is evident by the variety of services provided to Illinois citizens.

Accurate measurement and delivery of wholesale and retail commodities, monitoring the quality of motor fuel products sold within the state, and maintaining laboratories for metrology standards and grain moisture measurement are the statutory obligations of the bureau. Device inspections and metrology calibrations are performed at nominal fees, generating revenue in financial support of the program.

The Bureau licenses anyone who sells, installs, or repairs commercially used weighing or measuring devices through the Registered Serviceperson Program.
