Pressure & Vacuum Calibration
−12 psi vacuum to 10,000 psi against Fluke pressure standards
Pressure & Vacuum metrology at FCI
Pressure is a critical process and assembly measurement where an out-of-tolerance instrument can cause leaks, failures, or rejected lots. FCI calibrates pressure gauges, transducers, transmitters, and calibrators against Fluke reference standards traceable to NIST.
Our accredited pressure scope spans low-range work from 0 inH₂O to 10 inH₂O (0.031 inH₂O, Fluke 700P01/719) and −12 to 30 psi (0.018 psi, Fluke 717-30G), through 0–30 psia (0.021 psia, Fluke 700PA5), mid-range 30–1000 psi, and high-range work to 5,000–10,000 psi (8.1 psi, Fluke 700P31). Each range uses a dedicated Fluke reference module.
These certificates support process pressure-loop calibration, test-stand qualification, and assembly verification for aerospace, automotive, manufacturing, and energy customers. FCI's documentation is built for audit — an AS9100 or IATF 16949 auditor sees the test points, tolerances, and uncertainties they expect.
FCI provides in-lab calibration and on-site service for fixed pressure systems, with expedited and rush turnaround available when a critical instrument is holding up production.

Pressure & Vacuum calibration questions
What pressure instruments do you calibrate?
Pressure gauges, transducers and transmitters, pressure and vacuum calibrators, differential and absolute pressure instruments, and process pressure modules.
What pressure range is accredited?
From 0 to 10 inH₂O at the low end, vacuum and gauge from -12 to 30 psi, absolute from 0 to 30 psia, and gauge pressure up to 10,000 psi against Fluke 700-series reference modules.
Is pressure calibration traceable to NIST?
Yes. Pressure and vacuum measurements trace to NIST through Fluke reference pressure modules, reported at 95% confidence (k=2).
Can you calibrate fixed pressure systems on site?
Yes. We calibrate in the lab and on site for fixed pressure systems, with expedited and rush turnaround when an instrument is holding up production. Returning customers get a written quote within one business day. New customers and new equipment go through ISO/IEC 17025 contract review in three to five business days.
