The Checkline QB-LED is a hand-held, battery-powered stroboscope featuring forty (40) extremely bright LEDs for the highest light output in its class. Designed for machinery observation, visual inspection and motion analysis, its robust design is suitable for use in the toughest industrial environments.
The QB-LED features a robust aluminium housing fitted with forty long-life, high-performance LEDs providing a peak brightness of 5000 Lux and convenient adjustment of flash duration to easily select the optimal balance of brightness and image sharpness. A built-in Lithium-Ion battery provides up to seven hours of continuous use on a single charge. It is supplied with a universal battery charger (100-240VAC) with USA, Euro and UK plug adapters.
The strobe is extremely easy-to-use, as functions such as flash rate and brightness adjustments are separated from the special functions that are found 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.
