Ultraviolet Marking Kit Mark
Ultraviolet (UV) Marking Kit that includes a new dual function torch that can be used as a handy flashlight all year long. The other function is its UV LEDs that is used to fluoresce UV ink and other items that will fluoresce in the 396nM range. When shined on an item that has been written on with a UV pen, the virtually ‘invisible’ writing now jumps out at you and is clearly visible for all to see.
It comes with a practical gift box, three AAA batteries and three different coloured Ultraviolet Pens. There is a water-based yellow UV ink pen, a light blue oil-based pen and a hard-to-get red ink pen.
The Dual Function Torch has 12 LEDs, 3 of which are Ultraviolet LEDs, rated at 395nM, which is a good match for the UV pens. Push the on/off button once and the 9 white LEDs come on illuminating a small room nicely. Push the same button again and the white LEDs turn off and the 3 UV LEDs turn on.
