Weights & Measures Inspection and Exams

The Idaho State Department of Agriculture Bureau of Weights and Measures (ISDA W&M) examines all commercially used weighing and measuring devices used in the state of Idaho on an annual basis. The inspection includes testing the device for accuracy and ensuring the device complies with design, construction and installation requirements. Inspectors also test packaged products for net contents, sample octane, and investigate complaints pertaining to measurements.

Title 71 of the Idaho Code requires any commercially used weighing or measuring device to be tested by ISDA W&M. Devices tested include Retail Motor Fuel Dispensers (RMFD), scales-from small grocery store scales to 200,000 pound Vehicle scales, propane meters, bulk fuel and oil meters and any device used to measure or weigh. To schedule or request inspections, call the Bureau of Weights and Measures at 208-332-8690 or e-mail the appropriate local inspector.
