Weights and Measures Sealer
At a state or county weights-and-measures office, you inspect and certify commercial weighing and measuring devices — gas pumps, retail scales, taxi meters, vehicle scales — applying official seals that prove the device tests accurate within legal tolerance.
What it's like to be a Weights and Measures Sealer
A typical week often involves device testing, calibration with certified standards, sealing certified devices, and condemning failed equipment — testing retail scales with standard weights, testing gas pumps with calibrated provers, sealing or rejecting equipment based on results, writing reports that document each inspection. You're often the consumer-protection layer between commercial sellers and the buying public. Devices tested and accuracy compliance are the operating measures.
The harder part is often the physical demands of testing large devices — vehicle scales, lumber scales, and bulk gas-pump systems require moving substantial test standards, often outdoors in any weather. Variance across employers is wide: at large state offices the work runs on structured routes and specialized equipment; at smaller jurisdictions it tilts more generalist with broader scope.
The role suits people who are mechanically literate, physically capable, and disciplined in calibration practice. NCWM training and state weights-and-measures credentials anchor advancement. The trade-off is the physical work of handling test standards and the weather exposure that field testing consistently involves.
