Pocket Stroboscope

(adds Trigger Signal Output)
30 - 12,500 RPM/FPM
and higher using harmonics

The new PK2X hand-held Pocket Strobe® is convenient and accurate device to perform non-contact RPM measurements on rotating or reciprocating parts or components as well as a proven means for inspection of moving parts/machinery by freezing or slowing down the action. This stroboscopic effect is accomplished by matching the flash rate of the stroboscope with the repetitive rate (RPM) of motion of the target. A slow motion effect is accomplished with a slight mismatch of the relative speeds.

The PK2X is powered by a rechargeable internal battery or directly from an AC power source allowing for continuous use if necessary, or continued use when the battery charge is low. It small size, lightweight design makes it perfect for use by field technicians or maintenance personnel.

The new PK2X offer significant improvements from the previous generation model PK2 including the following (refer to table below): " 50% improvement in flash brightness " 100% improvement in battery run-time " Doubles the choice of power by permitting operation during re-charge or continuous operation when connected to AC-power

This new model continues to offer the highest reliability, refined by over 10-years of continuous design & manufacturing improvements since the introduction of the original Pocket Strobe Model PK1 was introduced in 1996.

The PK2 requires only one hand to operate, yet delivers performance comparable to much larger and heavier pistol-grip type models. It is ideal for industrial, laboratory, R&D and academic environments. Its small size and excellent performance provide superior convenience and value at a reasonable price.
