Tamper-Evident Seals for Gas Pumps, Utility Meters & Calibrated Equipment
Gas pumps, utility meters, and other equipment regulated under state weights-and-measures laws all have to be sealed after calibration or inspection, so it's obvious if someone tampers with them afterward. That requirement traces back to a national model standard used by regulators across the country.
General information, not legal advice — confirm current requirements with your state weights and measures office or calibration authority.
Calibration & Meter Seals
Intertronix's Secure.It sequentially numbered stickers are built for exactly this: tamper-evident labels with permanent adhesive and consecutive serial numbers you can log at the time of calibration, so a missing or broken seal is an immediate flag that a device may have been opened since. Available in multiple colors and stock quantities, ready to ship without artwork approval.
Why it matters
NIST Handbook 44 — the model weights-and-measures code adopted in whole or in part by all 50 states — requires that any weighing or measuring device with an adjustable component be built with a way to apply a security seal that must be broken before that adjustment can be made (General Code, Section G-S.8). Once a device passes calibration or inspection, an intact, sequentially numbered seal is what lets an inspector or operator confirm it hasn't been touched since.
