Testo 477 LED Handheld Stroboscope
The Testo 477 LED Handheld Stroboscope offers reliable touch-free speed measurement for moving equipment and turning systems. It gives accurate readings up to 300,000 fpm using a bright, changeable LED flash that makes rapid movements appear still. This makes it ideal for checking machine behaviour without stopping operations.
Built with an IP65-rated body, this device keeps out dust and splashes, making it suitable for both factory and field use. A large, clear LCD display shows live readings and status updates. Users can change the flash time easily with easy-to-use button controls. The display stays clearly visible in dim conditions, helping you quickly find any problems.
Accurate Analysis in Motion
The Testo 477 supports external control thanks to its trigger input and output, allowing integration with sensors or automated systems. It handles vibration and rotation checks even in hard-to-access areas without the need for reflective tape or machine downtime. Fast battery recharge times and the option to use standard AA batteries ensure flexible deployment.
Designed for Demanding Environments
From quality checks on textile machines to monitoring conveyor belts and identifying hotspots in rotating parts, the Testo 477 provides practical analysis with a long 5–11 hour battery life depending on power source. Its 1500 Lux output at 20 cm ensures every detail of motion is clearly illuminated for accurate assessment during use.
