Pressure Gauge Calibration Services

A gauge that reads 40 when the line is at 60 isn’t a gauge — it’s a liability with a dial.

ACS Calibration delivers NIST-traceable, audit-ready pressure gauge calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. Pressure calibration from full vacuum to 10,000 psi is on our accredited scope, so ISO/IEC 17025 accredited certificates are available on request.

Instrument Types

Pressure Instruments We Calibrate

If it reads in psi, bar, kPa, inches of water, or torr, we can almost certainly handle it.

Frequently serviced brands: Ashcroft, Dwyer, WIKA, Omega, Enerpac, U.S. Gauge, McDaniel Controls, GP:50, IFM, and Welch Allyn — plus dozens more.

Accredited Pressure Capability

These ranges appear on our PJLA scope of accreditation — verify it independently anytime. Coverage runs from full vacuum to 10,000 psi, and metric-unit instruments (bar, kPa, MPa, inH₂O) are calibrated to the same points.

Why It Matters

Why Gauges Lie, and How We Catch It

A Bourdon tube work-hardens with every cycle. One overpressure spike bends the pointer or pegs the movement. Vibration wears the gearing until the needle sticks and jumps. The result is a gauge that looks fine and reads wrong — on a boiler, a compressor skid, an autoclave, or the test bench your quality system depends on.

We calibrate every common configuration: dry and liquid-filled analog gauges, digital test gauges, sanitary and diaphragm-seal gauges, oxygen-service gauges. Each is tested at multiple points rising and falling — so hysteresis shows up in the data — with as-found and as-left readings documented on the certificate.

The whole span from full vacuum to 10,000 psi is covered by our accredited capability, from low-pressure pneumatic gauges and differential pressure gauges to high-pressure hydraulic gauges. Behind the dials we also calibrate transducers and transmitters and digital indicators — and onsite calibration covers gauges that can’t leave the process.

Deliverables

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
The ACS Difference

Why Companies Choose ACS for Pressure Gauge Calibration

NIST-Traceable, Accredited on Request

Every calibration is NIST-traceable with real measurement data. Pressure calibration from vacuum to 10,000 psi is on our ISO/IEC 17025 accredited scope — accredited certificates available whenever your quality system requires them.

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.

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.
