SU-400 Dynasonic Hardness Tester is a universal portable durometerwith twin—testing-method. It applies twin-method aboutstate ultrasonic contact independence: UCIand dynamic rebound: Leebto make hardness testing in one instrument, it solves the dilemma that Leeb method can not test the hardness of plating and coating(in UCI), and UCI method can not test the coarse crystal material in the casting industry(in Leeb).
SU-400 can not only work with the UCI motorized and manual probes, but also work with theLeeb impact probe, it is universal to test the hardness of material with the fine crystalstructure or coarse crystal structure in the metal industry.
SU-400 UCI probe system is perfect to measure hardness testing about the coating and plating, which can measure the hardness of chrome, copper plating, carburized layer and Nitriding layer effectively.
SU-400 dynamic Leeb probe system is suitable to measure hardness of coarse material, such as, casting and forging
SU-400 is a NDT durometer due to the contact indention is too small to observe, it is one of the excellent solution to test hardness of finished products, such as, the mold, gear, shaft, rod, screw, rails, etc.
SU-400 conforms the standard ASTM A1038-2005, DIN standard DIN50159-1-2008 and China National standard GB/T 34205-2017, GB/T 17394.
