In stock

Testo 477 led handheld Stroboscope is used if the goal is to look at quick-moving things in slow motion. Next to alternative hand-held stroboscopes, this strobe will solely be operated with one hand. One will track their behavior safely and smoothly, check protocols properly and verify unwanted noise sources, etc

Applications: Industry, Research & Development, in Laboratories and Universities.

Testo 477 LED Stroboscope allows the motions to seem incredibly fast and sluggish. this allows you to manage and examine machines and systems throughout the operation and to live speeds of up to three hundred,000 rpm. The optic cannot say if a knitting machine’s thread guide works properly. this can be conjointly so not possible to mention that there are unit anomalies in instrumentality or structures vibration or stroboscope processes. however, the Testo 477 LED stroboscope is another matter. The strobe creates a series of flashes that look to you like a ‘frozen image. The LED Testo 477 can even calculate the spinning speed of terribly little objects. And as reflex marks aren’t needed, the devices should not stop and production processes should not be interrupted either.
