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.

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 measurement can be taken simply by clipping the wire. The instrument quickly displays the phase detection results and three phase voltage values.

A red light and a continuous buzzer sounds to indicate the Negative phase.

You can switch screens and check the frequency.

Phase detection check and line-to-line voltage inspection at the same time.

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.
