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. It makes stunningly fast movements appear as if they are in slow motion. For measuring speeds of up to 300000rpm and inspecting machines and systems while they 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. A trigger input and output ensure connectivity to external systems and control via an external sensor. The LED stroboscope’s integrated impact protection and sturdy IP65 rated housing (can be wiped down) ensure that TESTO 477 can stand up to the rough and tumble of everyday use. The longer battery operating time, can carry out uninterrupted measurements for up to 5hours.
