Visible Penetrants

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.

Met-L-Chek® VP-302

Met-L-Chek® VP-302 is a special application high temperature inspection penetrant. Commonly used in field weld and weld repair inspection, VP-302 is also used in the inspection of refinery processing equipment at elevated temperatures. Met-L-Chek VP-302 reduces inspection process time by eliminating the total cool down period required for standard penetrant.
