4D Technology designs and manufactures surface gauges and surface roughness profilers for accurate measurement of precision surfaces.
The 4D InSpec Surface Gauge is the first handheld, precision instrument for non-contact measurement of surface features and defects. With micrometer-level resolution, portability, affordability and ease-of-use, the 4D InSpec brings high resolution 3D measurement to the factory floor, and in machine shops and in field service applications. Measure pits, scratches, nicks, dents, bumps, rivet depth, dot peen depth, etc., from 0.0002” to 0.1” (5 µm–2.5 mm) deep or tall. The 4D InSpec is far more repeatable and accurate than visual comparison techniques typically used for surface defect measurement. Unlike high-end metrology systems it is rugged, flexible and affordable, to measure features on a wide range of part geometries, in the most challenging environments.
