Fluke 820-2 LED Stroboscope

The Fluke 820-2 LED Stroboscope is a rugged, compact, and highly efficient diagnostic tool designed for non-contact measurement of the rotational speed of machinery and moving components. Featuring a high-intensity 7-LED array delivering up to 4,800 Lux at 6,000 FPM/30 cm, it allows technicians to visually freeze motion, diagnose mechanical issues, and measure speed — without stopping equipment or applying reflective tape.

With a wide flash rate range of 30 to 300,000 flashes per minute (FPM), the Fluke 820-2 is ideal for applications in predictive maintenance, R&D, and process troubleshooting. Its quartz-controlled timing system ensures outstanding accuracy within ±0.02%, while the digital pulse-width modulation technology produces sharper images at high speeds.

Designed to withstand demanding industrial environments, the Fluke 820-2 features a solid-state LED system with no filaments or hollow cavities and has been drop-tested to 1 meter for durability. The intuitive interface, multi-line LCD display, and push-button controls — including 2x and ÷2 adjustment buttons — make operation simple and efficient. Whether you are diagnosing parasitic oscillations, belt slippage, or gear misalignment, the 820-2 LED Stroboscope delivers clear, reliable, and repeatable results.
