District businesses must register all Universal Product Code (UPC) scanners, pharmaceutical balances, scales used in dialysis clinics, and commercially used weighing and measuring devices including gas pumps, produce scales and many other devices. DCRA inspects thousands of devices twice every year to validate that the devices are properly calibrated and display accurately.

• Our inspections of retail engine fuel meters ensure that you get what shows on the pump. We also check storage tanks to be sure there’s no water in the gas.
• When you buy foods by weight, like meat, fruit, and vegetables, the grocer uses scales we’ve checked for accuracy.
• We inspect packages to make sure they weigh what their labels say they weigh.
• Stores that use price or UPC scanners must pass our inspections: their shelf prices must match their scanned prices.
• By inspecting jewelers' balances, we ensure that gems and precious metals are weighed accurately.
• We inspect prescription balances, so pharmacists can weigh medicine mixtures accurately.
• We inspect compressed natural gas meters to make sure you get what you pay for.
• We help ensure safe health care by inspecting the dialysis clinic scales used to check patient weights
  before and after treatment.
• We inspect hopper scales, so concrete, sand, gravel, and asphalt mixtures are measured correctly – before they go into streets, sidewalks, and buildings.
• Our vehicle scale inspections help businesses comply with highway load restrictions – and assure accurate pricing of sand, gravel, asphalt, and scrap metal.
• We inspect commercially-used yard sticks and tape measurers – used to measure fabric, building materials (screening, glass, piping) and other products sold by the inch, yard, and foot.
