Hioki PD3259 Digital Phase Detector

Hioki’s non-contact voltage detection and measurement technology places efficiency and safety as priority considerations with the goal of protecting customers that need to conduct on-site electrical work as part of renovations and expansions of manufacturing plants and buildings. The PD3259 Digital Phase Detector lets you to measure three-phase voltage and detect phase sequence simultaneously by just clipping onto covered cables, ensuring absolutely no contact with metal parts for maximum safety.

CAT IV 600 V

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.

Simultaneous display of phase order, ground phase, and 3-phase voltage values

Phase order, ground phase, and 3-phase voltage values are displayed at the same time on a large, easy-to-see display that can be used as-is to create photographs to document electrical installations.

Easy-to-understand visual and aural communication of judgment results

The PD3259 indicates phase order (normal/reversed) judgment results via the color of its backlight and a beeping sound.

[Normal phase order]
Backlight: Green
Beeping: Intermittent tone

[Reversed phase order]
Backlight: Red
Beeping: Continuous tone
