PRYDE Measurement has released the Tritronics Smarteye Stealth-UV Sensor. It is designed to detect the presence of invisible fluorescent materials contained in or added to chalks, inks, paint, greases or glue. It can also detect optical brighteners found in labels, paper, tape and string.

The sensor contains an ultraviolet (UV) solid-state light source that is used to excite the luminescent materials to fluoresce in the visible range. The sensor's detector then responds to the visible fluorescing light. When the received fluorescing light level (displayed on the contrast indicator) reaches a level of “four" or above, the NPN and PNP output transistors will switch to the opposite state.

The sensor is immune to most ambient light, including indirect sunlight and strobes.
