The hand-held, battery-powered Checkline Europe QBS-LED is a stroboscope equipped with 118 extremely bright LEDs for the highest light output in its class. (Peak Brightness of 10,000 LUX)
It has been specifically designed for use in motion analysis, machinery observation and visual inspection, its robust design is well suited for use in the most demanding industrial environments.
It is the first measuring device of its kind to be equipped with an auto-sync laser function. This allows for the synchronisation frequency to be determined very quickly, without manual adjustment or external sensor signals.
Furthermore, the additionally generated value guarantees absolute measuring certainty.
The QBS-LED comes with a sturdy aluminum housing fitted with 118 long-life, high performance LEDs providing a peak brightness of 10,000 Lux and a user-friendly adjustment of flash duration to select the optimal balance of brightness and image sharpness.
A Lithium Ion battery provides up to seven hours of continuous use on a single charge.
The strobe is easy-to-use, as functions such as flash rate and brightness adjustments are separated from the special functions that are found in a separate menu.
The special functions include phase shift, internal/external trigger selection, flash delay, divider and "Slow Motion" mode.
The QBS-LED uses the "strobe effect" whereby -when the flash rate is equal to the rotational speed-, the target will appear "frozen".
Typical applications include: motion and vibration analysis, balancing of rotating shafts, fans, cams, high speed motion analysis of speakers or ink-jet printing and more.
Ideal for use in the textile, paper making, sheet metal production, automotive and printing industries.
The QBS-LED is supplied as a complete kit including:
All supplied in a foam-fitted plastic carrying case.
