Dimensional Calibration

Masters, Tool and Gage Calibration

Micrometer calibrationThe calibration lab at Laboratory Testing Inc., known as LTI Metrology, has been serving varied industries with dimensional calibration services and certified reporting for years. LTI Metrology is a leading, full-service calibration lab with the credentials and services to assure your measuring hand tools and instruments measure precisely and efficiently. Our dimensional calibration services include tool calibration for a variety of measuring hand tools from calipers and stop watches to angle plates and irons, as well as micrometer calibration, gage calibration (gauge calibration), and calibration of masters and standards.

The Dimensional Calibration Process

Dimensional calibration is performed by comparing the performance output of a hand tool, gage or another measuring instrument with a measurement standard to confirm that the item produces results which meet or exceed that standard’s criteria. The details of these results are clearly reported on your Calibration Certificate, along with as found” and “as left” conditions, our NIST-traceable standards, A2LA accreditation and any adjustments or repairs made during tool or gage calibration. The varied list of items that we calibrate dimensionally and mechanically includes:

Masters & Standards

  • Gage Blocks to 20 inches
  • Length Standards/Micrometer Standards to 120 inches
  • Pitch Micrometer Standards
  • Profilometer Standards
  • Surveillance Masters
