County Weights and Measures Inspectors inspect and test various types of weighing and measuring devices throughout the county. Examples of some of the types of devices inspected are: gasoline dispensers, propane/butane meters, electric meters, taxi meters, odometers on ambulances, farm milk tanks, pharmacy scales, deli counter scales, livestock scales, concrete batch plant scales, truck scales, etc. All such devices are under the scrutiny of weights and measures. They are tested for accuracy and inspected to determine if they are appropriate for their intended use. Once that is determined, the inspector certifies the device by affixing a paper seal to it.
