The Fluke 9040 is an accurate and robust tool for measuring and displaying phase rotation direction in three-phase AC systems.
This device is specifically used for the installation, servicing, and troubleshooting of three-phase motors, electrical panels, and industrial energy distribution systems.
With its simple and rugged design, the Fluke 9040 can quickly detect phase sequence without the need for external power. Simply connect the three probes to the phase terminals to determine the rotation direction (clockwise or counterclockwise) and verify the presence of all phases on the display.
The large and clear LED display, along with a wide working voltage range (up to 700V AC), makes this tester ideal for industrial environments, facilities, and production centers.
