QB-LED Portable Battery powered LED Stroboscope
The hand-held, battery-powered Check-Line QB-LED is a stroboscope featuring 40 extremely luminous LEDs for the highest light output in its class.
It has been designed specifically for machinery observation, visual inspection and motion analysis and its robust design is suitable for use in the toughest industrial environments.
The QB-LED features a sturdy aluminum housing fitted with forty long-life, high performance LEDs providing a peak brightness of 5000 Lux and a user-friendly adjustment of the flash duration, to select the optimal balance of brightness and image sharpness.
The built-in Lithium Ion battery provides up to seven hours of continuous use on a single charge.
It 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. "Slow Motion" mode allows the user to offset the flash rate to put the "frozen" image into virtual "slow-motion".
The QB-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.
