Calibration on your terms: in our lab, at your line, or door to door.

Laboratory Calibration

Our Placentia facility houses 8,000 sq ft of laboratories environmentally controlled to each measurement discipline’s requirements, running both manual and automated verification and calibration with some of the latest metrology equipment available.

On-Site Calibration

When downtime isn’t an option, our technicians come to you, equipped with NIST-traceable standards to calibrate at your facility. Our scheduling specialist will book a date that works around your production; we recommend reserving about 3–4 weeks ahead.

• Emergency calls: after-hours and weekend service is available when you’re in a bind.
• Service minimums: $275 dimensional/mechanical, $400 electrical, $800 RF, plus round-trip travel at $1.80/mile ($65 minimum).

We cover all of Orange County and Los Angeles County on-site.

Free Pickup & Delivery

Your instruments ride in our delivery vans with our drivers, not in a courier’s parcel stream. Scheduled routes cover the greater Los Angeles area every week:

Email customerservice@americangage.com or call (657) 216-2600 to get on a route. Walk-in drop-offs are always welcome. Just include a PO or packing list.

Full route detail city by city is on our service areas pages.

Repair & Refurbishment

We evaluate before we repair, and our estimates never exceed 50% of the new cost of the unit. Past that, we’ll tell you the honest answer: it’s beyond economical repair.

Hand tool & dimensional gage repair

Full repair service for precision hand tools — calipers, micrometers, indicators, height gages, and more. Every hand tool is cleaned and lubricated as part of calibration; minor repairs and battery replacement are included for most brands, and we stock replacement parts for Mitutoyo, Starrett, Interapid, SPI, and other major manufacturers so worn tools are repaired and re-certified in the same visit.

Surface plate resurfacing

Small granite plates are lapped to ±0.0001 in when needed; larger plates are resurfaced to the desired class. Badly pitted or out-of-tolerance plates get a straight recommendation for factory regrinding.

Electrical repair

Certified repair technicians handle major adjustments and board-level work. The evaluation fee is waived when you approve the repair. Reach the repair department at repair@americangage.com.

Hardness tester repair

Repair and calibration service for hardness testers of all major types.

Related services: surface plate resurfacing, hardness tester repair, Mitutoyo service and Starrett service.

Process Troubleshooting & Uniformity Surveys

Our process technicians troubleshoot process controls, heaters, ovens, and instrumentation to help you comply with GMP, USP, SAE, BAC, Nadcap, AMS 2750, and related standards. We perform oven and chamber temperature uniformity surveys (including AMS 2750 surveys for aerospace heat-treatment), and re-program controllers, recorders, and data acquisition systems.
