Model FL5000 Fluorescence Inspection Light

Model FL5000 Inspection Light

The BlueLine Model FL5000 is not an ultraviolet light – it is a blue light for fluorescent NDT inspection that works with existing fluorescent particles and penetrants. The blue light excites the fluorescence of the materials and the BlueLine filter glasses completely block the reflected blue so that you see your fluorescent indications with maximum contrast. The FL5000 incorporates a unique selectable flashing mode that makes it much easier to see indications when there is ambient light present.
