Form gages and form gaging systems are used to inspect parameters such as roundness, angularity, squareness, straightness, flatness, runout, taper and concentricity. 

Dimensional gages and instruments provide quantitative measurements of product or component dimensional and form attributes such as wall thickness, depth, height, length, inner diameter (ID), outer diameter (OD), taper or bore

Thread gages are dimensional instruments for measuring and/or verifying thread size, pitch or other parameters

Masters and setting gages provide dimensional standards for calibrating other gages

Surface profilometers are contact or non-contact instruments used to measures surface profiles, roughness, waviness and other finish parameters

Surface metrology equipment is used to measure the surface finish and/or geometry of engineering components. Surface texture and topology characteristics include surface roughness, contour, form, waviness and defects

Plug and pin gauges are used to compare hole and slot dimensions or locations to specific tolerances. This product area includes go gauges and no-go gauges. 

Specialty or proprietary gages, instruments or gaging systems for dimensional measurement

Metal balls and spherical shapes are used as check or ball valves, bearings, or other applications. Metal bearing balls are precision ground for ball bearings or other motion systems

Dimensional measurement and metrology services use mechanical gaging, CMM measurement, non-contact imaging or other specialized methods to inspect and measure part dimensions and geometry

Calibration standards and reference sources include any source that can provide a reference for the calibration of an instrument or comparison of a material or component.

Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources.

Dimensional and profile scanners gather two-dimensional (2D) or three-dimensional (3D) information about an object.

Optical flats or test plates are polished surfaces that are used as references against the flatness of unknown surfaces for comparison. They use the property of interference to measure the flatness of a test surface

Styli and probes are slender, rod-shaped stems and contact tips or points used to probe surfaces in conjunction with profilometers, SPMs, CMMs, gages and dimensional scanners
