Top-Loading Balance Calibration Services
Fast, forgiving, and everywhere — which is exactly why they drift unnoticed.
ACS Calibration delivers NIST-traceable, audit-ready top-loading balance calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. Balances from 2 g through 3,000 g are on our accredited scope, so ISO/IEC 17025 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.
The Balance Everyone Uses and Nobody Watches
Top-loading balances are the utility players: open pan, quick tare, weigh and move on. They take spills, overloads, and constant handling that an analytical balance would never see — and because the readings “look fine,” months of gradual drift can pass without anyone questioning the numbers.
We calibrate top-loaders with certified weights across repeatability, eccentricity, and linearity, with as-found and as-left data recorded — so the drift that accumulated between calibrations is on paper, not in your product. The 2 g to 3,000 g span is covered by our accredited capability.
Calibrate the whole bench at once: precision and analytical balances, benchtop scales next door in the packout area, and everything in between — in-lab or onsite.
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
Why Companies Choose ACS for Top-Loading Balance Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. Balances to 3,000 g and scales to 750 lb are on our ISO/IEC 17025 accredited scope — accredited certificates on request, with NIST-traceable coverage to 5,000 lb.
4–6 Business Day Typical Turnaround
Keep production moving. Most instruments are typically completed in 4 to 6 business days from arrival, with rush options available when a line is down.
Flexible Logistics
Mail your instruments in, or schedule onsite calibration and we come to your floor — serving Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and beyond.
