Field Instruments

The Fluke 9040 Phase Rotation Indicator is a reliable and professional instrument designed to determine phase sequence and rotation direction in three-phase electrical systems.

Built for industrial environments, the Fluke 9040 provides clear and accurate phase indication using a high-visibility LCD display, enabling technicians to quickly verify correct wiring and motor rotation.

Unlike battery-powered devices, the 9040 operates directly from the system under test, ensuring maintenance-free operation and enhanced reliability. Its robust design and wide voltage range make it ideal for use in industrial, commercial, and maintenance applications.

Key Features

• Three-phase indication with clear identification
• Displays phase rotation direction (clockwise / counterclockwise)
• Large, easy-to-read LCD display
• No battery required (powered by test circuit)
• Suitable for high-voltage industrial applications
• Fast and accurate phase sequence determination
• Robust and reliable Fluke design
