4D InSpec® Surface Gauge
The 4D InSpec surface gauge is a ground-breaking 3D optical gauge that enables high-resolution, non-contact surface defect and feature measurements right on the shop floor.

Product Overview
The 4D InSpec optical surface gauge is the first handheld precision instrument designed for non-contact surface defect measurement. With micrometer-level resolution, portability, affordability and ease-of-use, the 4D InSpec surface gauge brings high resolution 3D surface measurement where it’s needed: on the factory floor, in machine shops, and in field service applications.
This surface gauge provides 3D surface measurements to instantly quantify defects and features up to 100 mils (2,540 micrometers) deep. Without the need for replication, it can measure large components of varying complex geometries directly. It is adaptable for handheld use, workstation setups, or robotic operation with optional accessories to meet specific customer challenges.
Even with its incredible precision and extensive analysis capabilities, its ease of use allows non-experts to take measurements after just minutes of training.
Applications
- Pits and scratches
- Nicks, dents and bumps
- Edge break, radii and chamfers
