The testo 477 LED strobe makes surprisingly fast movements seem like slow motion. This allows you to inspect and verify machines and systems while they are still running and measure speeds up to 300,000 rpm. It is also possible to measure the rotational speed of very small and hard-to-reach objects. And because there is no need to reflect the mark, there is no need to stop the machine, nor to interrupt the production process.
