Weights & Measures

Weights & Measures works to ensure a fair market so that the products you buy are accurate in price, label, weight, and measure.

We do this by testing each commercial scale, meter, and device, as well as verifying prices and point-of-sales systems in San Diego County. We also inspect gas pumps and other petroleum products, weighmaster stations, and product labels and packaging to make sure that you get what you pay for.

Next time you're at the market or the gas station, look for the official seal and notice above on your pump, scale, or register to know it's been tested by a County Weights & Measures inspector, as well as who to contact if you've been overcharged.
