Connecticut Scale Certification & Weights and Measures

✓ Verified from official sources — July 11, 2026

Connecticut runs a state-managed weights and measures program — commercial scale owners deal with the state agency directly. If you operate a commercial scale in Connecticut — at a warehouse, farm, recycling yard, retail store, or truck stop — here is who regulates it, what the law requires, and exactly who to contact.

Who inspects commercial scales in Connecticut?

State-run program: DCP's Standards Program is responsible for ensuring the accuracy of all weights and measures used in Connecticut trade and operates the state's only metrology laboratory; there is no county/municipal inspection layer to contact. Scale owners contact the DCP Food and Standards Division (860-713-6160, dcp.foodandstandards@ct.gov).

What Connecticut requires of scale owners

DCP registers/licenses 'Operator of Weighing & Measuring Devices' for businesses using commercial devices, and separately licenses Dealers and Repairers of weighing/measuring devices and Public Weighmasters; applications are filed by PDF or online at elicense.ct.gov, with renewals and reinstatements through DCP License Services.

Devices used to buy or sell by weight must comply with NIST Handbook 44 — in practice this means an NTEP-certified, legal-for-trade scale. Confirm requirements for your device class with the office listed here.

Getting a scale into service — 4 steps

  1. Buy a legal-for-trade (NTEP-certified) scale appropriate for your application and capacity.
  2. Confirm registration and licensing requirements with the Connecticut Department of Consumer Protection (860-713-6160) before the scale enters commercial use.
  3. Arrange compliant installation and calibration. Where required, placing-in-service must be done by a licensed or registered service company.
  4. Stay compliant. Pass required inspections, keep calibration current, retain service records.
