Discover the 3R-SU Dynasonic Hardness Tester – your universal, portable hardness tester with dual test method

The 3R-SU Dynasonic hardness tester offers you state-of-the-art hardness testing in a compact, portable device that combines two test methods in one: ultrasonic impedance (UCI) and the dynamic rebound method (Leeb). This innovative twin method overcomes the limitations of conventional hardness testing methods.

Thanks to the UCI method, you can precisely measure the hardness of coated materials such as chrome, copper plating and carburized layers – perfect for fine crystalline structures. At the same time, the Leeb method enables reliable testing of coarse crystalline materials such as cast and forged parts.

The 3R-SU series is compatible with motorized and manual UCI probes as well as Leeb “impact probes” and offers a universal solution for the metal industry. Whether fine or coarse crystal structures – the 3R-SU series measures the hardness of your materials precisely and reliably.

The device complies with international standards ASTM A1038-2005, DIN50159-1-2008 and GB/T 34205-2017, GB/T 17394, making it the ideal choice for hardness testing of end products such as molds, gears, shafts, rails and more.

Rely on the 3R-SU series for fast, precise and “non-destructive” hardness testing – anywhere, anytime!
