NIST-traceable calibration and repair for pressure gauges across 15–5,000 PSI — precision built on digital reference standards and a grandfather's name.
Formed in Mississippi to carry forward a family trade — pressure gauge calibration done the way it was taught, by hand, checked twice, and never shipped out the door until it's right.
AccuGauge exists because a grandfather spent a career making sure gauges told the truth — and because that standard was worth keeping. Every instrument that leaves this shop is checked against a reference chain that traces back to NIST, the same discipline he worked by.
That's the whole business: no shortcuts on test uncertainty ratios, no gauges returned "close enough." If a reading can't be trusted, it doesn't leave calibrated — it gets repaired, re-checked, and documented until it can be.
Based in Olive Branch and serving the Memphis Mid-South, AccuGauge calibrates and repairs pressure gauges for shops and facilities that can't afford a reading being wrong.
From routine certification to full teardown repair, every gauge is handled on-site with documented, traceable results.
Pressure gauges calibrated across 15–5,000 PSI against traceable digital reference standards, with full TUR documentation.
Bourdon tube, movement, and case repair for gauges that fail calibration — restored to spec rather than replaced whenever possible.
Every calibration ships with a documented certificate — reference standard used and full traceability chain.
Standing intervals set to your QA program, with records kept and due dates tracked so nothing runs out of cert unnoticed.
Reference standards are chosen for the pressure range being tested, not used across the board, so the test uncertainty ratio holds at every point on the gauge.
Reference standards include a 300 PSI precision digital gauge for low- and mid-range work and a 5,000 PSI standard for high-pressure test points — each selected to keep uncertainty ratios tight across the whole range.
Bring gauges to the Olive Branch shop, ship them in from anywhere in the U.S., or ask about on-site calibration for equipment that can't easily travel.
Send over what you need checked and how many gauges, and you'll hear back with turnaround and pricing. Drop off in Olive Branch, or ship gauges in from anywhere in the U.S.
