Pocket Strobe™ PK-2 Pocket Stroboscope

click for improved version PK2X



Pocket Stroboscope

CHE.PK2-OT (adds Output Signal and Jack)
30 - 12,500 RPM/FPM
and higher using harmonics

The CHECK•LINE® Pocket Strobe™ Model CHE.PK2 is a highly stable instrument for taking non-contact RPM measurements and inspecting moving parts by “freezing” or “slowing down” the action.

The CHE.PK2 requires only one hand to operate, yet delivers performace comparable to much larger and heavier “pistol-grip” type models.

The CHE.PK2 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.


Internal NiMH battery provides one hour of continuous operation, regardless of flash rate

Bright (800 Lux) flash intensity with life of 100 million flashes

Resolution of ±1 RPM over the entire range with highly accurate speed control and drift-free operation

Fits in pocket or can be worn on optional belt holster—small and light for portable, one-hand use

Accepts input from sensor for external flash triggering

CE Certification

Free NIST Certification


  Stroboscope, battery charger, external triggering jack, NIST-traceable calibration certificate and instruction manual, all supplied in a hard shell carrying case.
