On-Site Calibration Services

Your instruments never leave the building. Your production never stops. Our technicians bring the accredited lab to your floor.

ACS Calibration runs on-site calibration routes across Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and Louisiana — NIST-traceable, audit-ready, with ISO/IEC 17025 accredited certificates available on request for instruments on our scope. Find your city or request a visit.

Instrument Types

What We Calibrate at Your Facility

Everything that’s bolted down, built in, or too busy to ship — plus the bench instruments we can do while we’re there.

Frequently serviced brands: Mitutoyo, Fluke, Ohaus, Snap-on, Ashcroft, Mettler Toledo, and Tinytag — plus dozens more.

Why On-Site

Some Instruments Can’t Ship. None of Them Have To.

Floor scales are bolted to the dock. Environmental chambers are mid-study. Analytical balances lose their calibration the moment a courier tosses the box — and a wall of RH sensors isn’t going anywhere. On-site calibration exists because the alternative — downtime, freight risk, and monitoring gaps — costs more than the visit.

Our technicians arrive with NIST-traceable reference standards and work your list in one pass: the weighing room, the QC lab, the production floor, the maintenance crib. Sensitive instruments get calibrated in the environment where they actually work — which is best practice for balances and fixed sensors anyway — and as-found/as-left data goes on every certificate, same as in-lab.

Scheduling is built around your operation: single visits, standing route stops, or a whole-facility annual event that puts every department on one due date. Anything better served by the lab rides back with us and returns calibrated — one vendor, every instrument.

The Visit

What an ACS On-Site Day Looks Like

  • Scheduled around production — nights, weekends, and shutdown windows included
  • Calibration in place for balances, chambers, and fixed sensors — best practice, not just convenience
  • Whole departments done in one pass, aligned to one due date and one certificate package
  • Monitored spaces stay covered — loggers and sensors rotate so compliance never goes dark

ISO/IEC 17025 Accredited & NIST-Traceable Calibration

Every calibration performed by ACS is backed by strict quality management systems, technical competence, and full traceability to NIST standards. For assets or ranges outside our accredited scope, we provide documented NIST-traceable calibration with identical data rigor — or accredited third-party calibration through one of our approved vendors, reviewed by our QA team.

How It Works

Calibration Without the Hassle

1. Ship It or Schedule Us

Send your instrument to our Dothan, AL laboratory — or book onsite service and we come to your facility.

2. NIST-Traceable Calibration

ASQ Certified Technicians calibrate your instrument against NIST-traceable reference standards — in our lab or at your facility.

3. Audit-Ready Certificate

Your instrument returns with a NIST-traceable certificate documenting as-found and as-left data. ISO/IEC 17025 accredited certificates available on request.
