The test methods mentioned enable quick and mobile measurement with a Leeb hardness tester or an ultrasonic hardness measuring device, as a supplement to the classic stationary hardness test. Thanks to the compact and different measuring probes, the devices can also be used in difficult test positions and component geometries. Areas of application are e.g. incoming goods inspection, mix-up check, production control, quality assurance, weld inspection, cut edge inspection, gear wheel inspection, maintenance on installed components.
