Met-L-Chek® Visible penetrants are widely used in general industry for spot inspections of welds, equipment repairs, safety checks, through leak testing of heat exchangers, field tests in oil and gas equipment, and nuclear component casting inspection. The red penetrant indications are readily visible in bright white light and sunshine contrasting with the white developer.
The visible penetrant test method lends itself to field applications where there are limited infrastructure resources such as electricity or water and requires limited instruction in use. All the needed materials, cleaner/removers, penetrants, and developers, come in aerosols for ease of application and storage.
