The new ST-320BL Black Light LED Stroboscope provides light in the Ultraviolet spectrum required to illuminate UV Inks used in security tags, watermarks, labels and more. The ST-320BL can be used as a hand-held portable strobe or fixed-mounted for continuous use. It features long-life LEDs that provide even light distribution and don't require replacement like conventional xenon type strobes.

Operation is simple using an 8-button keypad and quick rate adjustment dial, combined with large, backlit LCD display. Phase shift, flash duration and flash rate are all quickly adjustable. It also features "x2" and "1/2" keys to quickly "double" or "half" the flash rate to identify the correct flash frequency. The unit can be externally-triggered from a remote sensor. The Wide Flash Range 60 – 120,000 Flashes/min. (1-2000 Hz) can be adjusted to meet almost any high-speed application.
