The Starrett HDV250 is a next-generation digital comparator designed to modernise 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.
The HDV 400 Horizontal Digital Video Comparator combine the best features of a horizontal Optical Comparator and a Vision metrology system. The HDV is configured like a traditional horizontal comparator. The workstage is the same as the Starrett field-proven compartors. The heart of the HDV system centers on a uniquely patented designed interchangeable lens mounting system coupled to a hi-resolution 5 mega-pixel digital video camera. The system is available with a choice of seven telecentric lenses for micron-level resolution and optical distortion as low as 0.001% for accurate field-of-view (FOV) measurements. With MetLogixTM M3 software, DXF CAD files can be imported and 2D Go/No-Go digital overlays can be developed directly from the CAD files. Video edge detection (VED) allows real-time interaction of the imported file with the video image of the part being inspected. Productivity, speed, and accuracy are all enhanced. Systems are available in maunual or CNC control.
The HDV500 CNC Digital Video Comparator offers the best features of a large, floor standing, horizontal Optical Comparator and a Vision metrology system. The HDV500 has a long 20” x 8” (500mm x 200mm) X-Y stage and heavy-duty steel construction. The workstage is the same as the popular HF600 and HF750. The heart of the HDV system centers on a uniquely designed interchangeable lens mounting system (patent pending) to a hi-resolution 5 mega-pixel digital video camera. The HDV500 is available with a choice of three telecentric lens options for micron-level resolution and accuracte field-of-view (FOV) measurements. With MetLogixTM M3 Metrology software, DXF CAD files can be imported and 2D Go/No-Go digital overlays can be developed directly from the CAD files. Video edge detection (VED) allows real-time interaction of the imported file with the video image of the part being inspected. Productivity, speed, and accuracy are all enhanced.
