Differential Pressure Gauge Calibration Services

Filter loading, room pressurization, flow — DP gauges live on small numbers with big consequences.

ACS Calibration delivers NIST-traceable, audit-ready differential 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

Small Pressures, Serious Stakes

Differential pressure gauges do quiet, critical work: Magnehelic-style gauges watching filter loading and cleanroom pressurization, DP instruments across orifice plates metering flow, isolation-room monitors a hospital audits monthly. The full-scale reading is often less than half a psi — a range where most calibration providers are guessing.

We’re not: the low-differential band down to a fraction of a psi appears specifically on our accredited scope, and inches-of-water-column instruments are calibrated to the same points. Every gauge is tested at multiple points rising and falling with as-found and as-left data, so trend drift is on the record before it becomes a failed room-pressure check.

DP instruments usually work alongside pneumatic gauges, compound and vacuum gauges, and DP transmitters — one shipment or one onsite visit covers the set.

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 Differential 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.
