Vacuum Gauge Calibration
On-site and off-site vacuum calibration of vacuum gauges, controllers, and ancillary instruments. Using our state-of-the-art vacuum calibration station, we calibrate gauges from every major manufacturer — Edwards, Leybold, Pfeiffer, Agilent, MKS, Inficon, and more — with a documented certificate per gauge.
Vacuum calibration is the comparison of a customer's vacuum gauge or vacuum-measuring instrument against a certified reference standard, with a calibration certificate issued documenting the gauge's accuracy at one or more reference pressures across its measurement range.
On-site visits 5–10 working days from booking; off-site calibration typically 5 working days from receipt at our workshop.
- •Multi-point calibration with documented certificate
- •Reference standards traceable through the UK national measurement system
- •Suitable for ISO 9001, ISO 17025, IATF 16949, NADCAP quality systems
What you get with vacuum calibration
Multi-point pressure calibration
Gauges calibrated at multiple reference points across their measurement range — typically 5 to 10 points spanning atmosphere down to ultimate vacuum, depending on gauge type.
Calibration against certified standards
Our calibration station references certified standard gauges with traceability through the UK national measurement system.
On-site calibration available
For gauges that can't easily be removed (or where downtime to remove them is expensive), our engineers can travel to your site with portable calibration equipment.
Off-site calibration at our workshop
For benchtop calibration of multiple gauges or where gauge accuracy demands a stable environment, customers ship gauges to our Sutton Coldfield workshop.
Calibration certificate per gauge
Documented certificate showing reference pressures, gauge readings, deviations, environmental conditions during the test, and the next-calibration-due date.
Repair and adjustment if out of spec
Where a gauge is found to be out of spec, we offer adjustment, repair, or replacement.
From booking to handover
- 1
1. Booking
Tell us the gauges (make, model, serial number), measurement range, and whether you need on-site or off-site calibration.
- 2
2. Pre-calibration check
Each gauge inspected and zeroed before calibration, environmental conditions logged.
- 3
3. Multi-point calibration
Gauge connected to our calibration station and read against the reference at each calibration point.
- 4
4. Certificate issued
Calibration certificate produced per gauge, including all reference pressures, deviations, and the next-calibration-due date.
- 5
5. Return (off-site) or sign-off (on-site)
Off-site: gauges returned with their certificates. On-site: certificate handed over and gauge re-installed.
When you'd typically need vacuum calibration
Common scenarios where customers ask for this service. If your situation isn't listed but sounds related, get in touch — we can advise.
- Annual recalibration to support ISO 9001, ISO 17025, IATF 16949, or NADCAP quality systems
- After a process upset, contamination event, or shock that may have affected gauge accuracy
- Commissioning new vacuum equipment where gauge accuracy is critical to process control
- Periodic verification of central CMVS or vacuum-furnace gauges where drift would compromise the process
- Pre-audit calibration before a customer or regulatory inspection
