The Checkline QBS-LED is a hand-held, battery-powered stroboscope featuring 118 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 QBS-LED features a robust aluminum housing fitted with forty long-life, high performance LEDs providing a peak brightness of 10,000 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.

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.

Built-In Laser Light Source provides a Non-Contact "Tachometer Mode" when used in combination with reflective tape. It also features a unique "Auto-Sync" feature using the Laser Tachometer Mode to automatically set the correct flash rate to instantly "freeze" the rotating target without requiring any adjustment by the end-user. It also features a "Slow Motion" Mode that allows the user to offset the flash rate to put the "frozen" image into virtual "slow-motion".
