What American Calibration does

American Calibration, Inc. (ACI) is a U.S.-based accredited calibration services provider founded in 1992 by Todd Gibson and headquartered in Fox River Grove, Illinois (with an additional Crystal Lake office). The company delivers over 350 types of calibration across electrical/RF, dimensional, mechanical, thermodynamic, time and frequency, and chemical domains, serving customers in aerospace, automotive, medical, pharmaceutical, food and beverage, semiconductor, nuclear, energy, government, and law enforcement verticals. Core operations combine an ISO/IEC 17025-accredited in-house laboratory (temperature-controlled, with CMM, vision system, and ULM) with a nationwide mobile field-service network offering 24/7/365 emergency response and on-site accredited certification generation.

The company is differentiated by regulatory credentials — ISO/IEC 17025:2017 plus ANSI Z540.1 with a 40+ page accreditation scope, NADCAP SAE AMS 2750F certification for pyrometric standards, and first-in-USA accreditation for the Fluke 5560A Multi-Function Calibrator — and by a broad electronics laboratory suite (Fluke 5730A, 5790B, 52120A, 5725A, 732C, 742A, 910R, 7526A) plus a Clarke-Hess 6000A phase meter for sub-0.026 degree measurements. Supporting the core calibration offering are repair services, new and refurbished equipment sales, retrofitting/retrofitting, dimensional inspection, temperature/pyrometry (TUS/SAT), non-destructive testing, preventive maintenance, metrology consulting, equipment rentals and loaners, and customer portals (DataView and Gold Access) for 24/7 self-service. Pricing is quote-based with multi-year contract cadences and volume/multi-location discounts; standard turnaround is 3–5 days with 24-hour expedited service available.

Since September 2023, American Calibration has operated as a subsidiary of Concept, a Minneapolis-based advanced manufacturing solutions firm established in 1974. The acquisition brought ACI into a family of nine offices across 18 upper-Midwest states (alongside sister companies BC MacDonald, Metrology Center, Inspection Engineering, and Concept Advanced Manufacturing Solutions), expanding geographic reach and cross-referral capacity. The company serves over 2,000 customers ranging from Fortune 500 manufacturers to small/mid-sized industrial firms, and retains founder Todd Gibson as operating leader with stated operational autonomy under the parent platform.
