Description

Testo 477 LED Handheld Stroboscope

The Testo 477 LED Handheld Stroboscope performs non-contact rpm measurement of rotating components like propellors and flywheels via a high intensity (1500Lux) LED flash. The light is capable of up to 300,000 flashes per minute (fpm) with 0.02% accuracy and 0.1/1 fpm resolution. The flashing LED makes fast-moving mechanisms appear in slow motion meaning that any rotation and vibration can be measured and assessed during operation.

The Testo 477 has a trigger input and output which means it can be connected to an external sensor or system. It has a large digital display that shows the fpm value and the user can adjust the flash duration and frequency via the simple push-button interface.

A long 5-hour battery life is extremely practical and the Testo 477 also benefits from an IP65 ingress protection rating which makes it suitable for challenging environments. It is supplied with a battery, transport case, trigger signal connector and calibration protocol.
