The Extech PQ3350 3-phase power & harmonics analyzer offers power measurements of single and 3-phase/3-wire or 3-phase/4-wire systems. The PQ3350 is also capable of data logging up to 52,428 single phase readings or 17,476 3-phase readings. The meter is available as a stand-alone unit or in two kit forms. Kit 1 includes 1200A 12" flexible current clamp probes (PQ3350-1) while Kit 2 includes 3000A 24" flexible current clamp probes (PQ3350-3). These flexible clamp probes can be used for wrapping around bus bars and wire bundles.

With a large backlit LCD display that shows up to 35 parameters on one screen, the Extech PQ3350 3-phase power & harmonics analyzer offers a simultaneous display of harmonics and waveform. Other features of the PQ3350 include clamp-on True RMS power measurements, display of waveform with peak values, analysis of total harmonic distortion and adjustable CT (1 to 600)and VT (1 to 3,000) ratios.

An optically isolated USB interface, with software, allows users to download waveforms, power parameters and harmonics from the Extech PQ3350 3-phase power & harmonics analyzer. Optional clamp probes are also available as accessories for the PQ3350, ranging from 100A to 3000A and allowing you to choose the best clamp probe to fit your application needs.
