Surface Defect inspection

Introducing 4D InSpec® defect gauge – new technology for fast, accurate and repeatable measurement of surface defects, scratches and corrosion.

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, the 4D InSpec brings high resolution measurement to the factory floor, in machine shops and in field service applications.

Use the 4D InSpec to instantly quantify defects such as pits, scratches, nicks, dents and bumps from 0.0002” to 0.1” (5 µm–2.5 mm) deep or tall. You can also measure features such as edge break, radii, rivet depth and part marking.

The 4D InSpec is far more repeatable and accurate than visual comparison techniques typically used for surface defect measurements. Unlike high-end metrology systems it is rugged, flexible and affordable, to measure a wide range of part geometries in factory environments.
