Capabilities
Nine disciplines. One accredited lab.
Each measurement discipline runs in its own environmentally controlled laboratory, because a mass lab held to ±0.5 °C and a salt bath at 550 °C don’t belong in the same room.

Calipers: Up to 60 in
Electrical / RF
RF automation: Automated MET/CAL RF racks
Temperature & Humidity
Temperature range: −196 to 1000 °C
Pressure
Range: −14.7 to 10,000 psi
Mass
Accredited class: ASTM / OIML Class 1
Pipettes
Method: Gravimetric & photometric (ISO 8655)
Force & Torque
Torque range: 0.5 ozf·in – 1,000 lbf·ft
Flow
Uncertainty (10–100% FS): ±0.25% of reading
Vibration
Method: Back-to-back comparison

How It Works
Three steps to audit-ready.
- 01
Send your equipment list
Manufacturer, model, serial. Spreadsheet or scribbles, we don’t judge. You get scope confirmation, pricing, and turnaround within one to two business days.
- 02
We pick up on your route
Our driver collects your instruments on the next scheduled run through your county, or drop off anytime, or book on-site calibration at your facility.
- 03
Certs land in your portal
Calibrated in 7–10 business days with as-found/as-left data, uncertainty, and NIST traceability, delivered back to you and accessible online 24/7.
Why American Gage
Big-lab accreditation. Small-lab attention.
The national calibration chains process enormous volume, which means your instruments are one barcode among thousands. We hold the same A2LA ISO/IEC 17025:2017 accreditation they do, but from one Placentia lab we deliver something they structurally can’t: a team that goes deep on every client’s program.
- You get a lab, not a queue
- At national chains your instruments enter a nationwide workflow. Here, the technician calibrating your equipment is a direct phone call away, and knows your account, your tolerances, and your audit schedule.
- Audit-ready evidence, every time
- Every certificate documents as-found/as-left data, measurement uncertainty, NIST traceability, and the Z540.3 decision rule with TUR, the package FDA, AS9100, and ISO 13485 auditors ask for.
- One-stop shop convenience
- Calibration, repair, process troubleshooting, and AMS 2750 surveys under one roof, so your equipment list doesn’t get split across three vendors.
