PHASE DETECTOR PD3129

Phase Rotation Meter with Easy-to-Read Arrow and Non-Metallic Contact Clips for 70V to 600V Lines

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 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.

A comment of Good Design Award 2016
“I was impressed by Hioki’s commercialization of no-metal-contact
voltage measurement technology, which not only eliminates the
risk of electric shock while performing electrical work in the
field, but also contributes greatly to reducing workload, both
psychologically and in terms of man-hours required to complete
a task. In addition, the product’s size and interface are well
considered in light of a basic design that differs from past
products due to the use of no-contact technology.”

CAT III 600 V

Key Features

• Simply clip clamps onto wire insulation
• Green LED arrow clearly shows phase direction, perfect for visual reports
• Rotating LED indicator shows the phase sequence for a 3-phase power supply at a glance
• Intermittent beeps signal positive phase; continuous tone signals reverse phase
• Magnetic base allows the instrument to be secured on a distribution panel

	Easy-to-understand detection of normal phase with lit arrow The arrow in the center of the instrument turns green to indicate normal phase. In this way, normal phase can be recognized at a glance. In addition, the arrow shows up clearly in photographs, making the PD3129 ideal for documenting proper installation in end-of-project reports. (Photo: 3129-10)
	Safe, no-metal-contact design The PD3129 uses no-metal-contact clips that need only be clipped to the outside of each insulated wire, allowing phase to be detected safely. (Photo: 3129-10)
	Magnetic back for maximum work efficiency Four magnets on the back of the instrument allow it to be secured in place on distribution panels. By leaving your hands free for other tasks, this feature dramatically boosts work efficiency. (Photo: 3129-10)
