a. Suitable for non-destructive testing of a wide range of metal, non-metal and composite materials;

b. Strong penetration ability, can detect the internal defects of the specimen within a larger thickness range. For example, for metal materials, it can detect thin-walled pipes and plates with a thickness of 1~2mm, and it can also detect steel forgings that are several metres long;

d. Higher detection rate for area-type defects;

e. High sensitivity, can detect defects of very small size inside the specimen; f. Low detection cost, fast speed, lightweight equipment, harmless to human body and the environment, more convenient for on-site use.
