Precision Metrology has a complete library of procedures, standards and specifications to assure that your gages are calibrated to meet specified class and designation. We pride ourselves in the attention and detail given to every gage, assuring that every calibration is performed with accuracy, precision and to your requirements. Prior to calibration sealing wax is removed and gages are cleaned, demagnetized, and inspected for wear. Gages are checked for nicks and burrs, which are stoned and removed as necessary. Every gage is stabilized at 20°C prior to calibration. Gages are entered into our Labmate Metrology Management system with proper description, sizes and nomenclature. For fixtures and functional gages, sizes and accuracy specifications are entered as a permanent part of our database for all subsequent calibrations. Prior to shipment critical gaging surfaces are coated in dipseal to prevent damage.

A certificate of calibration is issued for every instrument ID number along with long form readings. Every certificate of calibration issued by Precision Metrology meets or exceeds the requirements of ISO 17025 and ISO 9001:2008. All calibrations are performed using standards traceable to the NIST.
