• Non Contact Digital Phase Detector (1.5m lead length)
• World's first non-metallic contact voltage detection and testing
• Simply clip onto wire insulation
• Phase detection check and line-to-line voltage inspection at the same time
• Easy and intuitive phase detection check with backlight and buzzer

Phase detector + tester functionality: At-a-glance, no-metal-contact phase detection and line voltage measurement in 3-phase circuits.

With the PD3259, you can check both phase order and line voltages simply by clipping the sensors to the outside of the circuit's insulated wires. No-metal-contact measurement means maximum safety.
