Weights & Measures: Serving California Since 1850

The Sealer of Weights and Measures enforces laws and regulations that assure marketplace equity for transactions involving a count, weight, or measure.  Inspectors act as an impartial third-party promoting equity and integrity to protect both consumers and businesses in Solano County.  Every weighing or measuring device used in a transaction is held to a tolerance fixed tight enough that there is no serious injury to either the buyer or the seller, yet not so tight as to make manufacturing or maintenance costs of equipment disproportionately high.

The Division of Weights & Measures is responsible for regulating a diverse array of products and services.  Approximately 7,000 devices from over 600 businesses are inspected in Solano County every year.  Our inspectors also respond to complaints of discrepancies with these devices, credit/debit card skimmers, fuel quality, and more.  To file a complaint, please fill out the form below and email it to us.

If you wish to contact us, give us a call (707) 784-1310, or send us an email [email protected].
