Qnet P3124 Hardness Depth Tester

The P3124 is an ultrasonic non-destructive testing device developed in collaboration with the Fraunhofer Society for measuring Surface Hardening Depth (SHD). Unlike traditional destructive methods that are costly and limited to random sampling, the P3124 enables fast, reliable in-process hardness depth measurement.

The device works on the principle that hardened layers are nearly transparent to ultrasonic waves, while unhardened material scatters them back. The software processes the backscattered signal and automatically calculates the SHD value.

Key Features:

4 ultrasonic channels, IP65-rated industrial housing, portable design, 5–25 MHz inspection frequency range, and ±0.2 mm measurement repeatability. Includes "SHD-Studio" software with custom test programs, visualization/analysis tools, and individual report templates.

Typical Applications: Camshafts, crankshafts, linear guides, tulip joints, rings, and other surface-hardened components.

Advantages: Short setup times, simple calibration, high test sensitivity, adaptable sensors for complex geometries, testing at small radii and undercuts, line and circumferential scans, and automation capability.
