PK2X-OT Pocket Stroboscope With Output Signal

and higher using harmonics

The PK2X-OT hand-held Pocket Strobe® is a convenient and accurate measuring instrument for performing non-contact RPM measurements on rotating or reciprocating parts or components as well as a 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. Furthermore, a slow motion effect can be accomplished with a slight mismatch of the relative speeds.

The PK2X-OT stroboscope 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 power is low. Its small size, lightweight design makes it perfect for use by field technicians or maintenance personnel.

The PK2X-OT offers 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

The PK2X-OT continues to offer the highest reliability, refined by over 10-years of continuous design & manufacturing improvements since the original Pocket Strobe Model PK1 was introduced in 1996.

The PK2X-OT requires one hand to operate, yet delivers performance comparable to much larger and heavier "pistol-grip" type models. Ideal for industrial, laboratory, R&D and academic environments. Its small size and excellent performance provide superior convenience and value.
