The ST-320BL is a portable or permanent mount stroboscope.

Utilizing super bright high-powered black light LED lamps, these stroboscopes are perfect for UV ink printing applications. The ST-320BL’s LED array provides a bright, stable strobe light over a wide measurement range with a lifetime far exceeding xenon lit stroboscopes. Operation is simple with the 8 button keypad and quick rate adjustment dial, combined with large, backlit LCD display. Phase shift, flash duration, plus flash rate are all quickly adjustable. The unit can work off user adjusted flash frequency or from a remote sensor’s signal which will automatically adjust to corresponding process fluctuations.

The ST-320BL is designed for speed and frequency measurements in the printing, packaging, textile, automotive, cable, mining, steel, chemical, optical and medical industries in various applications.
