Manometer Calibration Services
Inches of water column, ounces of pressure — the small numbers that keep buildings breathing and processes safe.
ACS Calibration delivers NIST-traceable, audit-ready manometer 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.
Low Pressure, High Stakes
Manometers — digital, U-tube, and inclined — own the low end of the pressure world: draft on a combustion appliance, gas line pressure, duct static, filter loading, medical suction. Readings live in inches of water column, where a few hundredths matter and most calibration providers are outside their comfort zone.
Low pressure is precisely where our accredited scope is strongest: the sub-psi differential band appears on it explicitly, and manometers are calibrated at points rising and falling with as-found and as-left data documented. Digital manometers used for combustion and HVAC certification stay defensible from one heating season to the next.
Manometers share toolbags with differential pressure gauges and pneumatic gauges — one shipment or one onsite visit covers the set.
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
