Safe Non-Contact Phase Rotation Tester with True Voltage Measurement
Non-contact phase sequence tester with integrated voltmeter to check phase order, true line-to-line voltage, frequency, and missing-phase in three-phase systems, CAT IV 600 V, IP54, Bluetooth connectivity (Z3210 included)
• 90 to 520 V AC measurement range
• For insulated conductors from 6 mm to 30 mm diameter
• CAT IV 600 V safety rating
• IP54 dust/water resistant housing
• Bluetooth communication to smart devices (Z3210 included)
• Safe, non-contact voltage detection
• Phase sequence detection with true line-to-line voltage measurement
• Installation and maintenance of three-phase wiring and equipment
• Troubleshooting phase errors, supply interruptions, and missing phases
• Verification of EV charging stations and infrastructure
• Commissioning and inspection of machinery and plant systems
The PD3259-90 is a bundle that combines the PD3259-50 digital phase rotation tester for three-phase systems with the Z3210 Bluetooth adapter. Unlike basic devices that only indicate phase sequence, it also measures true line-to-line voltages, frequency, and missing phases. Since all of these values are obtained through non-contact measurement and in a single step, technicians save valuable time in their daily work while also reducing costs for installation, maintenance, and troubleshooting.
The non-contact voltage clamps can simply be placed around insulated conductors, eliminating the need to expose live parts. This makes phase and voltage checks quicker, safer, and possible even in situations where direct electrical contact would normally require higher qualifications or additional protective measures.
By combining the base unit with the Z3210 Bluetooth adapter, the PD3259-90 offers a practical all-in-one solution for field use. Rugged and reliable, it is rated CAT IV 600 V and IP54 for operation in demanding environments. With the Z3210 included, it connects instantly to smart devices, allowing measurements to be logged via HIOKI’s GENNECT Cross app on Android or iOS devices or transferred directly to Excel (HID) for straightforward documentation and analysis.
The PD3259-90 was designed and is manufactured in Japan at HIOKI’s own design center and factories, ensuring the highest standards of lasting precision, reliability, and quality.
