The Phase-Tell III is a battery powered, two-piece wireless phasing tool used to determine phase relationships on three phase power systems, overhead and URD applications. When contact is made with line voltage or elbow test points, the Phase-Tell III units compare transmitted data and then display the results via Red or Green LED lights and differentiated audible signals.

Flashing green lights indicate In-Phase. Flashing red lights indicate Out-of-Phase. Wireless units communicate up to three hundred feet apart. Both units are identical, no need to identify transmitter or receiver. Voltage range from URD test points to 500KV. Both units confirm the same phase readings. Rugged extruded aluminum enclosure.
