The Kyoritsu KEW 8035 Phase Indicator is an advanced non-contact phase rotation tester designed for safe and efficient testing of three-phase electrical systems without direct exposure to live conductors.

Utilizing electrostatic induction technology, the KEW 8035 allows users to determine phase rotation and detect open phases simply by clipping onto insulated cables—eliminating the need for metal contact and significantly enhancing operator safety.

With rotating LED indicators, audible alerts, and a magnetic back mount, this device is ideal for electricians and engineers working in industrial environments where safety and reliability are critical.

Key Features

• Non-contact phase detection using electrostatic induction
• Detects phase rotation (clockwise / counterclockwise)
• Identifies open/missing phase conditions
• Works directly on insulated cables (Ø2.4 mm to 30 mm)
• Rotating LED indication for intuitive phase sequence visualization
• Audible buzzer for clear status alerts
• Magnetic back mount for hands-free operation
• High visibility LEDs with super brightness mode
• Wide voltage range for industrial applications

How It Works

1. Clip Sensors – Attach clamps to insulated cables (no metal contact needed)
2. Power On – Device detects electric field automatically
3. Observe LEDs – Rotating arrows show phase direction
4. Listen Alerts – Buzzer confirms rotation and faults
5. Diagnose – Identify phase sequence or missing phase
