The FLUKE-820-2 is a rugged, portable LED stroboscope designed for stop-motion diagnostics and non-contact rotational speed measurements. It utilizes a high-intensity 7-LED array to achieve a wide flash frequency range of 30 to 300,000 FPM with a quartz-controlled accuracy of 0.02%. The solid-state LED design ensures durability against a one-meter drop, while digital pulse width modulation provides exceptionally sharp images at high speeds. Key features include a multi-line LCD, an external trigger input, and simple push-button operation for easy adjustment. This tool is ideal for a wide variety of applications, such as inspecting belt-driven machines, bearings, and gears, or diagnosing parasitic oscillations and slippage in industrial machinery.
