Digital Vertical Profile Projector (Optical Comparator) – QualiPP™ Ver 300 Series Applications
Machined parts and precision components
Measures external profiles, steps, radii, chamfers, and feature relationships without contacting the surface. This is useful for small parts where clamp pressure or handling could affect results.
Stamped, formed, and laser-cut parts
Checks outlines, slot widths, corner radii, and edge quality using projected contours for quick pass/fail decisions. Adjustable illumination helps improve contrast on reflective or dark finishes.
Tooling, dies, and fixtures
Verifies angles, contour geometry, and key dimensions during tool maintenance or first-article checks. Screen rotation measurement supports angle inspection when verifying profiles and setup geometry.
Plastics, rubber, and molded items
Inspects part outlines and 2D features where soft materials could deform under contact measurement. Surface illumination helps show molded details that are difficult to measure with hand tools.

Standards and Metrology References
- ISO/IEC 17025: common framework for traceable calibration and measurement confidence when the projector is included in a calibration program.
- ISO 1 (20 °C reference temperature): aligns with dimensional metrology practice when controlling measurement environments.
- ASME Y14.5 and ISO GPS practices: supports GD&T-based interpretation and reporting when parts are evaluated against drawings.
