Why Choose a Mobile Calibration Lab?
Some tools can't afford to sit on a bench. If a production line stops because a torque wrench is out of spec, you're not just looking at maintenance costs—you’re risking lost revenue and safety incidents. With mobile calibration, we eliminate that waiting period. You keep working. We calibrate on-site.
Reduce Downtime, Maintain Compliance
Equipment doesn’t always fail on your schedule. But routine calibration isn’t something that should wait. Our mobile calibration lab is equipped to meet ISO/IEC 17025 standards, providing traceable results without the need to send instruments offsite.
That means fewer disruptions, reduced labor shuffling, and no guessing about when tools will be back. Most on-site calibrations are completed the same day.
Fast Turnaround for Critical Tools
Time-sensitive industries rely on us for mobile service because we get in, calibrate, and get out without disrupting their flow. You don't need to wait three days. You don’t need to pull backup tools from storage. And you don’t need to move heavy equipment off your premises.
Need a technician on-site ASAP? Our scheduling team works hard to respond fast.
Convenience Without Compromise
You get the same technical precision you'd expect in a lab, without moving your instruments from the work floor. All work is documented with as-found/as-left data, NIST traceable results, and digital calibration certificates for your internal records or audits.
Our Mobile Lab is ISO/IEC 17025 Accredited

Continental Testing is accredited to ISO/IEC 17025, the globally recognized standard for laboratory testing and calibration. This accreditation demonstrates that our methods, reference standards, and competence undergo routine third‑party audits. Proficiency tests, uncertainty budgets, and equipment maintenance logs are reviewed and compared to strict requirements.
Types Of Calibration Services We Offer
We provide on-site calibration for calipers, micrometers, and torque wrenches, vital in manufacturing lines. A vehicle assembly plant, for example, benefits greatly from our torque wrench calibration services to maintain consistent bolt tension.
