Hioki PD3129-10 - Non-Contact Phase Rotation Meter (Large Jaws) Easy-to-read arrow indicator No-metal-contact design for the ultimate in safety Magnetic back for maximum work efficiency For thick conductorsHiokis 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.Phase detection by clipping onto live wires has always presented hazards to the field technician, often requiring other personnel to be on standby in case the traditional metal clips come into contact with exposed wires or conductors. The HIOKI Phase Detector PD3129-10 helps alleviate the extra costs and cuts labor hours by providing a safe way to detect phase sequence on distribution panels and motors by incorporating fully enclosed ABS-molded clips with absolutely no metal exposure. In the instrument, an electronic induction voltage sensor is employed to enable accurate phase detection of insulated conductors. This innovative technology has enabled HIOKI to provide CATIV600V/CATIII 1000V safety characteristics often required by large power utilities and similar potentially hazardous working environments.The Hioki PD3129-10 is designed to safely detect the phase sequence in three-phase circuits for electrical installation and maintenance. Conventional metallic-contact phase detectors are constructed with a voltage cable with standard metallic clips, requiring the technician to clamp onto exposed metallic parts of the conductor and introducin
