Bierer Cordless Phasing Tester – PD800W

Bierer Cordless Phasing Tester – PD800W

Phasing has never been easier with the Exclusive, Wireless Technology of the PD800W®Cordless Phasing Tester.

The PD800W® Cordless Phasing Tester accurately and easily operates in multiple applications including phasing, voltage detection, phase sequencing and phase angle indication. You will only need this one kit for three-phase secondary systems, capacitive test points, URD systems and overhead and transmission/substation systems. This unique tester operates like a conventional phasing tester, but does not require an interconnecting cable or extension resistors. Each probe is water resistant, has a strong construction designed to withstand wear and is completely shielded to minimize stray field interference. Each kit contains a Reference Probe(Transmitter), Meter Probe (Receiver), one straight probe adapter (81280LPM), one hook probe adapter (81280LHM), instruction manual, all stored in a padded case (PD800B).
