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. Model PD3129-10 is a non-contact phase rotation meter that detects the phase of electrical current flow within insulated wires without using metallic contact voltage clips. The green arrow indicates normal phase, which can be useful for visual reports that document the proper completion of electrical work.

Available on EnvMart, these Phase Sequence Indicators are designed for accurate determination of phase sequence in electrical systems. Hioki Phase Sequence Indicators provide high precision and reliability, making them essential for ensuring proper phase rotation and electrical system safety.
