The handheld tachometer uses the so-called "stroboscope effect" to analyse fast movements, vibrations or periodic processes. With the help of 9 high-intensity LEDs, the handheld tachometer generates short flashes of light with an illuminance of up to 1500 lx. These flashes of light are emitted in synchronisation with the frequency of the movement to be monitored until the object appears to stand still to the observer.

The handheld tachometer has a contact speed measurement. The measuring range of the contact speed measurement with the handheld tachometer is 0.5 … 99,999 RPM. In addition to the contact measurement, the speed can also be measured optically with the handheld tachometer.
