4D Technology designs and manufactures surface gauges, surface roughness profilers and other metrology instruments for non-contact, 3D measurement of precision surfaces.

The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact surface defect measurement. With micrometer-level resolution, portability, affordability and ease-of-use, 4D InSpec puts high resolution measurement where it's needed: on the factory floor, in machine shops and in field service applications.

The 4D InSpec instantly quantifies defects such as pits, scratches, nicks, dents and bumps, and measures features such as edge break, radii, rivet depth and dot peen depth, from 0.1 to 100 mils deep. 4D InSpec is far more repeatable and accurate than visual comparison techniques typically used for surface defect measurements. And unlike high-end metrology systems it is rugged, flexible and affordable, to measure a wide range of part geometries in the most challenging environments.
