The ATS Family of Companies conducts precision calibration services on various tools and measurement equipment. We calibrate both small items, such as digital calipers, and large items, such as hardness testers, optical comparators, and surface plates too large to be sent to a laboratory for calibration. For every calibration we complete, we supply clients with digital copies of due date reports, current asset status, calibration certificates, and asset history on our convenient web-based platform, iPortal.
