Description
Overview of Digital Phase Detector PD3259-50
The Hioki Digital Phase Detector PD3259-50 is engineered for professionals who prioritize safety, accuracy, and efficiency in three-phase electrical testing. Utilizing non-contact voltage detection technology, this advanced device allows users to measure three-phase voltage and detect phase rotation simultaneously—simply by clipping the sensors onto insulated cables. This eliminates any need to touch exposed metal conductors, ensuring maximum operator safety in industrial and construction environments.
Key Functionalities and Connectivity
The PD3259-50 features both phase sequence detection and line-to-line voltage inspection on a large, easy-to-read display. When paired with the Wireless Adapter Z3210, it supports Bluetooth® connectivity, enabling seamless data transfer to smartphones or tablets via the free GENNECT Cross app. This allows field technicians to monitor readings, analyze vector diagrams, check unbalance rates, and instantly generate reports in Excel® or PDF formats for documentation and compliance.
Safe and Intuitive Operation
With an intuitive clip-on sensor design and color-coded clips, this detector minimizes error and simplifies measurement processes. A bright backlight and audible buzzer help users confirm phase orientation instantly, even in low-light conditions. The instrument also includes a hold function, automatic power-off, and low battery warning for reliable field use.
Built for Durability and Efficiency
Compact and lightweight, the PD3259-50 is IP54-rated, offering dust and water resistance for harsh environments. Its rugged construction, drop resistance, and easy wall mounting capability using the optional Magnetic Strap (Z5020) make it a dependable tool for professionals in electrical inspection, maintenance, and installation.
