Legal-for-Trade Scale Calibration Services
When money changes hands by weight, the scale answers to the state — and to your calibration records.
ACS Calibration delivers NIST-traceable, audit-ready legal-for-trade scale services, available at the ACS central lab or directly on-site at facilities across the Southeast. Balances from 2 g to 3,000 g and scales through 750 lb are on our accredited scope — larger scales to 5,000 lb NIST-traceable — so accredited certificates are available on request.
Scales & Balances We Calibrate
From 0.1 mg analytical balances to 5,000 lb floor scales — if it weighs, we calibrate it.
Frequently serviced brands: Ohaus, Mettler Toledo, CAS, A&D Weighing, Rice Lake, Health-o-meter, ULINE, KERN, Chatillon, and Seca — plus dozens more.
Commerce by the Pound
Legal-for-trade scales — retail checkouts, deli and market scales, shipping counters, recyclers — sell accuracy as part of every transaction. Regulators inspect them periodically, but between inspections the accuracy burden is yours, and drift discovered at inspection time means findings, downtime, and re-tests.
We calibrate legal-for-trade scales with certified test weights, documenting corner-load, repeatability, and linearity with as-found and as-left data — accredited through 750 lb, NIST-traceable through 5,000 lb. Alabama Weights and Measures governs commercial placed-in-service rules; our certificates give your compliance file the measurement evidence it needs. NTEP-approved scales and bench scales are covered alongside.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
