Geometric Dimension Instrument Metrology and Calibration
Calibration services for gauge blocks, optical instruments, precision measuring instruments and equipment, line scale instruments, general measuring tools, various gauges, angles, surface roughness, flatness, straightness, and inspection tools for product testing.
Service Overview

Geometric dimension metrology, commonly known as dimensional metrology, has length and angle as its fundamental parameters.


Categorized by project, it includes:

  • Line scale metrology

  • End standard metrology

  • Linear expansion coefficient

  • Large-scale length metrology

  • Angle metrology

  • Surface roughness

  • Gear and thread metrology

  • Area and volume metrology

  • Form and position parameters such as straightness, flatness, roundness, perpendicularity, coaxiality, parallelism, and symmetry

  • Spatial coordinate metrology

  • Nanometer metrology

 

Geometric dimension metrology is widely applied, as most physical quantities are quantitatively described in the form of geometric dimension information. It holds a crucial position in metrology units.
