NTEP-Approved Scale Calibration Services
Type approval is the scale’s pedigree — calibration is what keeps the pedigree meaningful.
ACS Calibration delivers NIST-traceable, audit-ready NTEP-approved 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.
Approved Is Not the Same as Accurate
NTEP approval certifies a scale’s design for commercial use — it says nothing about whether your particular unit still weighs correctly after years of service. Scales used in buying and selling carry legal accuracy obligations, and routine calibration with certified test weights is how those obligations stay met between regulatory inspections.
We calibrate NTEP-approved scales with certified test weights — corner-load, repeatability, and linearity, as-found and as-left documented — accredited through 750 lb and NIST-traceable through 5,000 lb. For placed-in-service and registration requirements specific to commercial use, check with the Alabama Weights and Measures program; our documentation supports the compliance file either way. See also legal-for-trade scales.
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
