Alameda County has over 4,400 commercial weighing devices: devices used in establishing the quantity or measurement of quantities in computing any basic charge or payment for services rendered on the basis of weight. These devices include grocery store scales, vehicle scales, shipping scales, recycling scales, and livestock scales ranging in weight from 60 grams to 120,000 pounds. Each scale is tested for accuracy and specifications and to determine if it is appropriate for its intended use. If it passes these requirements the inspector "seals" the device by placing a paper seal on it.

If you think a device is not correct, contact the office of the Consumer Concerns/Complaints.

If you need a new commercial device inspected, contact us.
