The testo 477 LED Stroboscope makes high-speed movements appear frozen in time, allowing precise inspections, diagnostics, and rpm measurements—without stopping machinery or interrupting production. With a massive measurement range of up to 300,000 flashes per minute (fpm) and illumination up to 4800 Lux, it is designed for monitoring extremely fast, small, or hard-to-reach moving parts.
This powerful stroboscope requires no reflective markers, enabling seamless rotational speed checks on production lines and industrial equipment. The robust IP65 housing withstands harsh environments, while integrated impact protection guards against accidental shocks. Trigger input and output allow synchronization with external systems and sensors for automated or advanced measurement setups.
Its long operating times—up to 5 hours on AA batteries or 11 hours with the NiMH rechargeable pack—ensure uninterrupted inspections during intensive workflows.
