Non-Metallic Contact 70V to 600V Phase Detector
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 3129 is a non-contact phase detector that can detect the phase of electrical current flow within insulated wires without the use of metallic contact voltage clips.
• Rotating LED indicator indicates the phase sequence for a 3-phase power supply at a glance
• Intermittent beeps signal positive phase; continuous tone signals reverse phase
• Magnetic base lets you secure the phase detector on a distribution panel
• Simply clip clamps onto wire insulation
