Weights & Measures inspects and test all devices used in commercial weighing applications. This includes scales found at grocery stores, farmers markets, freight shippers, meat packers, fisheries, pharmacies, and jewelers. We use a 60,000-pound crane truck to test scales at wineries, vineyards, granaries, cement plants, and quarries. Livestock scales are inspected at ranches, feed lots, and the auction yard. Devices that do not pass inspection are taken out of service until they are corrected.
