D igital C omparator S ystem HDV HDV250

The Starrett HDV250 is a next-generation digital comparator designed to modernize traditional profile inspection while preserving the workflow operators trust. Built on the proven body and stage platform of Starrett legacy comparator systems, the HDV250 maintains familiar manual operation and crosshair-based measurement techniques — replacing projection optics and mirrors with advanced digital imaging technology. A high-resolution video camera and integrated LED ring surface illumination, derived from the HDV400 CNC series, deliver enhanced edge contrast and superior surface visibility. The system provides the same crisp silhouette view expected from a traditional optical comparator while enabling clear inspection of features that cannot be backlit. The HDV250 is engineered to be shop-floor ready and as durable as traditional projection systems. Optional clean air kits can also provide an additional barrier between the system’s internal components and the elements. With a compact footprint, reduced weight, and solid mechanical construction, it is well suited for real-world manufacturing environments.

By combining familiar operation with digital imaging, the HDV250 enables faster inspections, enhanced surface evaluation, and more consistent measurement results — all at a price point competitive with standard comparator systems.

Backed by over 140 years of Starrett metrology expertise, the HDV250 delivers inspection integrity and confidence for modern production environments.
