Fluke 820-2 LED Stroboscope Rotational Speed Diagnostics

Fluke 820-2 LED Stroboscope delivers accurate, non-contact rotational speed measurement and stop-motion diagnostics for maintenance professionals, engineers, and technicians. Designed for rugged industrial environments, it allows clear observation of machinery in motion without reflective tape or physical contact—making it ideal for troubleshooting, inspection, and process analysis.

Key Features

• High-intensity LED array: 7-LED light source delivering up to 4,800 lux at 6,000 FPM and 30 cm

• Wide flash rate range: Supports 30 to 300,000 flashes per minute (FPM) for low- and high-speed applications

• Sharp image clarity: Digital pulse width modulation provides exceptionally sharp images at high rotational speeds

• High measurement accuracy: Quartz-controlled system ensures 0.02% accuracy (±1 digit)

• Rugged solid-state design: Drop-tested to 1 meter with no filaments, gases, hollow cavities, or glass

• Clear visual interface: Multi-line LCD display for easy operation and readability

• Advanced timing control: Flash advance and retard functions for viewing gear teeth, cutting surfaces, and drifting components
