Wireless support Wireless communication capability for even greater convenience than PD3259 (legacy model)
Compatible with Wireless Adapter Z3210.
When the wireless adapter Z3210 is attached to the instrument, you can use Bluetooth® wireless communication.
By using the free app GENNECT Cross, you can check the measurement value, manage the data and create the report on smartphones and tablets easily.

Instantly create reports by a free app (GENNECT Cross)
GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports.
The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos.
Can also check the unbalance rate and vector diagram from the measurement data of PD3259-50.
(Wireless Adapter Z3210 is necessary)

Easily transfer measurement data to an Excel® file: Excel® Direct Input Function
Excel® Direct Input function allows you to input measurement values directly and automatically into an Excel® file once the instrument's auto-hold function is activated. (Wireless Adapter Z3210 is necessary)
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.
Just clip the wire
The measurement can be taken simply by cliping the wire.

Safe measurement without contact with metal
There is no metal exposure on the sensor.
You can measure safely without touching metal.

Display on a large screen
Phase detection check and line-to-line voltage inspection at the same time.

Light and sound notification
A red light and a continuous buzzer sounds to indicate the Negative phase.
You can switch screens and check the frequency.

Place the instrument to the wall
The Magnetic Strap Z5020 (optional) can be used to hang and fix the instrument to the wall.

Color clips are included to help identify the code
