In detail:
The PD3259-90 is a bundle that combines the PD3259-50 Digital Phase Detector for threephase 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. 

Faster, safer testing with non-contact clamps 

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 or transferred directly to Excel (HID) for straightforward documentation and analysis.

The PD3259-90 was designed in Japan and is manufactured at HIOKI’s own factories in Nagano Prefecture, ensuring the highest standards of lasting precision, reliability, and quality.
