    Fluke 4550041 Description

    Identifying the running speed of rotating equipment can be difficult, but the Fluke 820-2 LED Stroboscope simplifies the process allowing you to perform stop motion diagnostics without actually stopping, or making contact, with the machine you are working on. Whether you are trying to diagnose parasitic oscillations, slippage, or unwanted distortions, the 820-2 LED Stroboscope is the ideal front line troubleshooting, process or product research and development tool.
