Product Overview

The TESTO 477 is a LED stroboscope. TESTO 477 LED stroboscope allows performing inspections and quality control of machines and systems and rotational speed measurements on hard to reach, small and fast-moving objects while the machines are still running.

A very high measurement range of up to 300,000flashes per minute and a very high illumination of up to 1500lux allow to carry out rotational speed measurements of up to 300000rpm.
