PK2X Pocket Stroboscope

The PK2X Pocket Strobe is a highly stable instrument for taking non-contact RPM measurements and inspecting moving parts by "freezing" or "slowing down" the action.

The PK2X requires only one hand to operate, yet delivers performance comparable to much larger and heavier "pistol-grip" type models.

The PK2X 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.
