Laboratory Balance Calibration Services
Whatever the lab weighs — samples, standards, reagents — the balance is the quiet assumption behind the data.
ACS Calibration delivers NIST-traceable, audit-ready laboratory 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.
Defensible Data Starts at the Pan
In a GLP or GMP environment, the balance record is part of the batch record. When a deviation investigation opens, the first questions are always the same: was the balance calibrated, when, by whom, and what did the as-found data look like? A calibration certificate with real numbers is the difference between a closed investigation and an escalated one.
We calibrate laboratory balances of every class with certified Class 1 weights — repeatability, eccentricity, linearity — and document as-found and as-left readings on every certificate. Balances from 2 g through 3,000 g are on our accredited scope.
The lab rarely stops at one instrument: analytical balances, precision balances, pipettes, and pharmaceutical scales all ride the same cycle — in-lab or onsite at your bench.
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 Laboratory 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.
