Rev Tach IV


Rev Tach™ lV

Tachometer for measurement of Aircraft Propeller Rotation Speeds

General Description
The Rev Tach optical tachometer is designed to be used for measurement of aircraft propeller rotation speeds, up to 300,000 blade passages per minute.

Rev Tach is a recognized industry standard rotation speed calibration grade optical tachometer. It utilizes powerful micro-computer resources and state of the art optical detection circuitry.

The instrument is easy to operate – just set up, aim and read – from direct sunlight to near total darkness, in front, back or angled to the propeller, in flight or on the ground.
