QualiPP™ H412 Digital Horizontal Profile Projector

The QualiPP™ H412 is a large-format Ø412 mm horizontal optical comparator designed for high-efficiency 2D dimensional inspection. Perfectly suited for the shop floor or the lab, this system provides a high-contrast projection screen for inspecting threads, angles, and complex form features.

With the integrated QualiDigi™ DP400 Digital Readout and long-life LED technology, the H412 delivers sharp, non-contact measurement for parts that are too delicate or complex for traditional contact tools.

Primary Industrial Applications

Precision Tooling & Machining: Perform in-process and final verification of external profiles, radii, and feature locations.
Stamping & Forming: Rapidly check hole patterns and edge forms on thin metal parts without risk of deformation.
Injection Molding: Consistently measure parting lines, slot geometries, and complex plastic outlines.
Thread & Gear Inspection: High-magnification screen comparison for evaluating thread forms, chamfers, and pitch.
Batch QC: Streamline incoming inspections with fast 2D measurement and immediate data reporting.

Key Engineering Features

Precision Lifting System: Guided by cross-roller rails and a precision screw drive for smooth, stable vertical focusing.
High-Contrast Optics: Coated reflector optics reduce dust interference and ensure a sharp, bright projected image.
Adjustable Dual Illumination: Fine-tune independent LED contour and surface lighting to match reflective or dark workpiece finishes.
Digital Efficiency: The QualiDigi™ DP400 DRO supports rapid geometry calculations and angle evaluation.
Metrology Compliance: Built to support ASME Y14.5 (GD&T) interpretation and ISO 14253-1 pass/fail decision rules.
