Cordless Phasing Tester, Visual & Audible

The cordless AV800AU is designed to operate similar to a conventional phasing tester, but does not require an interconnect cable.

The unit consists of a Reference Probe (transmitter) and a Meter Probe (receiver) and will operate reliably at distances up to 30m. The phasing tester is useable from 120V to 800kV
