In industrial manufacturing and quality inspection, material hardness remains a critical indicator of mechanical performance. As China's leading testing equipment provider, Sinowon introduces its SU Series Ultrasonic Hardness Testers utilizing Ultrasonic Contact Impedance (UCI) technology. Designed for non-destructive testing, high accuracy, and portability, our solutions serve aerospace, automotive, energy, and metalworking industries with unmatched efficiency.

Firstly, it must be known what material is tested, please check the typical application in the following table, it will be helpful to choose right probe. If there is coating or plating on the specimen, it is better to choose the motorzied probe with minimum testing force, but you must consider the roughenss of suface. If the roughness is high, the light force probe is not suitable.
Secondly, if the speimen is small and massive, it is better to choose a stationary stand to make the testing relia
