Digital Vertical Profile Projector (Optical Comparator) – QualiPP™ V400 Series

Profile Projector (also called an Optical Comparator) is a non-contact measuring system that projects a magnified silhouette of a part onto a screen, so you can measure profiles, radii, angles, distances, and feature locations quickly and consistently. QualiPP™ V400 Series is built around a Ø400 mm projection screen, stable vertical lifting, and a Multifunction Digital Readout – QualiDigi™ Readout 400 digital readout for fast 2D measurement in production QC and metrology labs.

Designed for repeatable inspection, the system combines high-resolution optics, adjustable contour and surface illumination, and a robust cooling design to support long duty cycles. The platform is well-suited for routine dimensional checks, incoming inspection, and final verification when optical clarity and fast measurement matter.

Digital Vertical Profile Projector (Optical Comparator) – QualiPP™ V400 Series Applications

Dimensional inspection of stamped and machined parts: Measure outlines, hole-to-hole spacing, radii, chamfers, and angles on small-to-medium components using projected profiles and DRO readouts.
Cutting tools and toolroom verification: Check tool geometry, edge form, and included angles for cutters, punches, dies, and precision inserts without contacting the part.
Plastics, rubber, and molded components: Verify silhouettes, part symmetry, slot widths, and profile deviation on molded features where tactile probes may deform the surface.
Electronics and precision assemblies: Confirm connector features, small brackets, and precision subcomponents where quick pass/fail decisions support throughput.
Metrology labs and calibration workflows: Support comparison-based measurements with controlled lighting and stable mechanics for routine measurement documentation and traceable reporting practices.

Standards

ISO 1 (reference temperature 20 °C) for dimensional measurements performed under controlled conditions.
ISO 14253-1 (decision rules for proving conformance/nonconformance) for pass/fail evaluation logic in inspection reporting.
ISO/IEC 17025 (lab competence framework) when the system is used inside calibrated measurement workflows.
ISO 10360-7 can be referenced only if you also position this within imaging-based dimensional measurement context (commonly used for vision/imaging probing systems).
