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.
