Digital Phase Rotation Meter with
Three-Phase Voltage Measurement Functionality

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 PD3259-50 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

Key Features
• Wireless support. Transfers measurements to your smartphone or tablet. (Optional Wireless Adapter Z3210 is necessary)
• 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
• Ideal for work certification photos, offering simultaneous display of phase sequence and 3-phase voltage

Note: Only the voltage value is displayed when measuring a single-phase/3-wire circuit.

Model No. PD3259-50

When Z3210 is installed.

Wireless support Wireless communication capability for even greater convenience than PD3259 (legacy model)

Compatible with Wireless Adapter Z3210 (optional).

When the wireless adapter Z3210 is attached to the PD3259-50, you can use Bluetooth® wireless communication.

And using the free app GENNECT Cross, you can check the measurement value, manage the data and creat the report on smartphones and tablets smoothly.

How to Use the Hioki Digital Phase Detector PD3259-50

In the past, four steps have been necessary in order to check a 3-phase power circuit: one set of measurements to check the phases with a phase detector, and three line-voltage measurements (one for each phase) made with a tester. The Digital Phase Detector PD3259-50 replaces this process with a single, no-metal-contact measurement step that can be made simply by affixing three clamp sensors. The instrument quickly displays the phase detection results and three phase voltage values.
