Most commodities, either as finished goods or during the stages of their manufacture, are weighed and valued according to the measurement. Therefore, the accuracy of all commercially used weighing devices in Montana has an enormous economic effect on both consumers and industry.
On an annual basis, inspectors from the Building & Commercial Measurements Bureau will test, inspect, and certify over 10,000 scales. These range from small jewelry scales with a capacity of 1,000 grams to large belt scales found at the coal mines capable of weighing 7,000 tons of coal an hour. Other examples of common scale types we test are the 30 pound capacity scales typically found at the check stand in your local grocery store, hopper scales used to weigh fertilizer, livestock scales located on ranches, rail scales used to weigh railroad cars and large truck scales used to weigh raw and finished products in the timber, grain, and mining industries. Each of these scales is tested every year using certified test weights ranging in size from small metal foil weights weighing .001 of a pound to large weight carts with block weights weighing 25,000 pounds.
