Businesses in the City of Madison must license all of their weights and measures devices, including scales, gas pumps and meters, scanner units, timing devices, and yardage measures. A license fee will be charged for each device, and devices will be inspected annually. See license application for specific fees.
The device seller should provide a copy of the certificate of conformance (COC). The COC guarantees the device has been tested by the National Institute of Standards and Technology and is adequate for retail use.
Licensing and inspecting devices protects consumers from unfair practices and gives them confidence in the business. It also helps businesses guarantee accuracy in their practices.
