About Cornerstone Metrology Service

What We Do

Cornerstone Metrology Service is a full physical/dimensional/electrical metrology laboratory with measurement capability to perform calibrations  in compliance  with the ISO / IEC 17025-2017, ANSI/NCSL Z540-1, ANSI/NCSL Z540.3,  ISO 9001-2015, and the  Mil.Std 45662a.                                                                                                                                   


In addition,  we sell,  service, and repair nearly all types of precision measuring equipment, including granite surface plate resurfacing.


Approximately  80%  of our  customers  are  military, aircraft or  aerospace, we  service  all  commercial,  medical,   automotive,  api  and  computer  applications  as well.
