4D Technology designs and manufactures surface gauges, surface roughness profilers and other metrology systems, for accurate measurement of precision surfaces. 4D products use patented technology to bring high resolution measurement to production environments, even in the presence of severe vibration and turbulence.
The 4D InSpec Surface Gauge is the first handheld, high resolution instrument for non-contact measurement of surface features and defects. With Portable, affordable, and easy to use, the 4D InSpec puts high resolution measurement on the factory floor, in machine shops and deployed environments. Measure pits, scratches, nicks, dents, bumps, rivet depth, dot peen depth, etc., from 0.1 to 100 mils deep. The 4D InSpec is far more repeatable and accurate than visual comparison techniques often used for defect inspection. Unlike high-end metrology systems it is rugged, flexible and affordable, to measure features on a wide range of part geometries, even on curved surfaces, on blind features or inside of bores.
