-
Touchscreen Display & Easy Operation: Large high-resolution color touchscreen for intuitive navigation, live statistics, and clear graphical displays.
-
Non-Destructive (NDT) Testing: Employs a vibrating Vickers diamond indenter leaving an almost invisible microscopic indent, keeping the test object fully intact.
-
Comprehensive Probe Compatibility: Works seamlessly with manual probes (10N, 20N, 50N, 100N) and motorized probes for specific roughness and micro-load testing requirements.
-
Automatic Multi-Scale Conversion: Instantly converts measured Vickers (HV) values to Rockwell (HRC, HRB), Brinell (HB), and Tensile Strength (N/mm²).
-
Advanced Data Management: Features internal memory capacity, USB interface, and PC software for detailed data evaluation and custom report generation.
Application Areas & Examples
The BAQ AlphaDur 3 is designed for demanding industrial applications where precision and surface protection are critical:
-
Heat-Treated & Hardened Components: Hardness depth profiling of induction-hardened gears, shafts, crankshafts, and camshafts.
-
Weld Seams & HAZ Testing: Point-by-point hardness mapping of weld joints and Heat-Affected Zones (HAZ) in pipelines, pressure vessels, and steel structures.
-
Injection Molds & Tooling: On-site inspection of plastic injection molds, stamping dies, nitrided layers, and repair welds without component disassembly.
-
Thin-Walled Parts & Turbine Blades: Precision NDT measurements on thin pipes, sheet metals, turbine blades, and delicate coatings.
-
Shop-Floor Quality Assurance: Direct in-situ evaluation of non-removable machine beds, heavy axles, and assembled structures.
