Ardrox 9VF2 is a high sensitivity azo-dye-free red penetrant which can also be used with an ultraviolet light to give improved indication of the defects.
In view of its red and fluorescent modes of operation the need for separate red and low sensitivity fluorescent penetrants is no longer required when ARDROX 9VF2 is used
During inspection of a component, if there is any doubt concerning an indication in the red mode, then the added sensitivity of the fluorescent mode should be used
