Micro Quality Calibration ("MQC") is at the forefront of the Metrology industry with a primary standard calibration service offering and capabilities unmatched among its peers. Our A2LA ISO/IEC 17025-2005 accreditation mandates us to uphold the highest level of quality assurance, documentation, and accuracy so that you can rest assured your equipment will be serviced to the highest quality disciplines while our staff provides exceptional service and keeps you updated on your equipment.

Our Primary Standard Laboratory boasts the most accurate precision measurement test equipment to meet or exceed the most demanding uncertainty requirements bestowed on us by our customers. All primary standard calibrations are performed in our environmentally controlled climate (both temperature and humidity are closely monitored 68°F with relative humidity not to exceed 40%) to give the lowest degree of measurement uncertainty.

We utilize Primary Standards traceable to one or more of the following:

  • Direct accredited calibration to National Bureau Standards
  • Direct Traceability to N.I.S.T.
  • OEM accredited calibration



Preparation of your precision measurement test equipment is just as important as the calibration. Preparation varies and is equipment specific. Any test instrumentation is thoroughly cleaned and inspected and allowed typically 24 to 72 hours to stabilize the temperature of the gage. This is done to obtain the most accurate measurement. When the gages are calibrated they are demagnetized and inspected for nicks, burrs, corrosion, and any other damage that may hamper accuracy and repeatability. Once calibrated, they are certified (with data) and oiled and packaged ready to be shipped to the customer.

Should your precision measurement test equipment be damaged or out of tolerance weoffer replacements. Please inquire with one of our service representatives for more information.
