Principle of Ultraviolet Light
UV Light radiates UV-A (center of wave distribution is 365 nm) and makes fluorescent materials in the flaw indication emit visible light. UV Light is

Testing method using electro-magnetic induction is generally referred to as “Electro-magnetic Testing Method”, and for the purpose of detecting surface and subsurface flaws it is
This testing method is called MT (Magnetic Testing) or MPT (Magnetic Particle Testing), and suitable for the surface / subsurface flaw inspection of ferromagnetic materials.Principle
So called PT (Penetrant Testing) or LPT (Liquid Penetrant Testing), this method can be applied to the surface flaw inspection of almost every materials and
