The SMS-400B Handheld Stroboscope is suitable for non-contact RPM measurements and for observation of fast, repeated motions of machines, their moving components or handled material from a distance of 20 to 50 cm, the revolving or oscillating machine component can be visualised as a stop motion picture by adjusting the light flashes synchronously to the rate of the movement.

With the multiplier / divider function, the actual RPM or frequency of the motion can be determined accurately. The phase-shift function enables visual positioning of the observed component, as well as the incremental observation of a complete course of motion in 5° steps, due to its flash rate with low deviation from the actual motion frequence, the courses of motion can be observed under a slow-motion effect.


  • High illuminance for industrial applications
  • Easy one hand operation with x2 and ÷2 buttons for a rapid increase / decrease of FPM and fine adjustments
  • Removable and rechargeable NiMH-battery with long operation duration
  • Phase-shift function for position adjustments and slow-motion effects
