Testo 477 LED Stroboscope
Includes: Testo 477, transport case, trigger signal connector, battery and calibration protocol.
The Testo 477 LED hand stroboscope is used when it is necessary to make fast-moving objects appear in slow motion. Testo 477 visualises rotation and vibration movements and allows measurement during continuing operation. The static image allows the inspection and qualitative evaluation of components moving at high frequencies.
You can also use the testo 477 to seemingly "freeze" the movement of an object. Without making contact with the object, you can precisely determine its rotational speed or the frequency of shifts in direction. Compared to other portable stroboscopes, the Testo 477 LED stroboscope can be operated with just one hand.
