Gauge Repair Service is accredited by the American Association for Laboratory Accreditation to perform the following mechanical¹ calibrations:

¹ This laboratory offers commercial calibration service and on-site calibration service, where noted.

² "Best Uncertainty" is the smallest uncertainty of measurement that a laboratory can achieve within its scope of accreditation when performing more or less routine calibrations of nearly ideal measurement standards of nearly ideal measuring equipment. Best uncertainties represent expanded uncertainties expressed at approximately the 95% level of confidence, usually using a coverage factor of k=2. The best uncertainty of a specific calibration performed by the laboratory may be greated than the best uncertainty due to the behavior of the customer's device, to the environment (if the calibration is performed in the field) and to the influences from the circumstances of the specific calibration.

³ On-site calibration sevice is available for this calibration. The uncertainties achievable on a customer's site can normally be expected to be larger than the Best Measurement Capabilities (BMC) that the accredited laboratory has been assigned as Best Uncertainty on the A2LA Scope. Allowance must be made for aspects such as the environment at the place of calibration and for other possible adverse effects such as those caused by transportation of the calibration equipment. The usual allowance for the uncertainty introduced by the item being calibrated (e.g. resolution) must also be considered and this, on its own, could result in the calibration uncertainty being larger than the BMC.

⁴ In the statement of best uncertainty R is the numerical value of the resolution of the device in microinches.
